Firefox Customizations (Notes)

My notes on customizing the Firefox web browser, blocking ads, invoking Notepad, customizing the built-in searchbar, copying and pasting formatted links.  A major portion of this document relates to my choices of Extensions as well as orientation within Firefox toward tutorials, and how to help. 

Additional pages cover Setup (initial installation), Toolbars & Context menus, Bookmarklets, Bookmarks, Keyboard shortcuts, Keyword shortcuts, and Tabbed browsing.  -- Special Topics:  Firefox 3 Introduction (TCF-NJ presentation/introduction) for both beginners and advanced users, and preferred use Styles instead of using userChrome.css (same coding).

Information found on this page includes:  An IntroductionFirefox notesCustomizations of Firefox and some specific extensions (Launchy, CopyURL Plus), Invoking Notepad, Extensions with short descriptions for my choices, accessing an additional home page by changing the throbber

Organization of this page:  Generate the Table of Contents (Alt+O) for this page and other webpages by installing the HeadingMap extension, then from the View menu → Sidebar → HeadingsMap (Alt+O).  Headings on this web page have a slight color tint:   h2   h3   h4 ; an on hover:  h2   h3   h4 

These notes should save you time finding materials to run Firefox like you want it.  Most of the browser features and shortcuts are the same in any browser, so using or switching to Firefox should not be a problem.

This page includes everything needed to install Firefox and describes most of the customizations I've made on my system including descriptions of over 300 extensions on this page which I've used and am currently using about 87 of them in Fx 4.0  In other words there is not much point to a list of a mere 5 or 10 top extensions, many of which may eventually be incorporated in Firefox.  The beauty is that many people have written code to enhance Firefox, and you can pick and choose what is suitable for your own usage.   Customization you will not find here are: RSS feeds, Themes, music, audio, visual.  Nor will I get involved with those lists of why others might prefer Firefox.

Where to get Firefox and Updates   (#wheretogetfirefox)

Firefox: The latest version is Firefox 4.0 updates to Firefox itself appear to be coming out about the middle of each month.  Use Firefox - Rediscover the web to download the latest Firefox 

Updates to Firefox and extensions can be checked automatically through setting in Tools → Options → Advanced → Updates or manually through Help(Alt+H) → About Firefox.

Old versions:  The problem often turns out to be something else, but if you want to restore an older version, you will probably find it in your downloads; otherwise, start at then choose version, platform (win32), language (en-US).

Bleeding Edge and Release Candidates not for general consumption:

Firefox Information/Features/FAQ at Mozilla and Mozillazine   (#info)

Mozilla:  [Features] [FAQ fx4] [FAQs] [Tools, Options] [fx4 Release Notes] [Mobile (Android)] [keyboard shortcuts] [menu]; 
Mozillazine KB:  [Firefox] links to problem solving (issues); and, installation and customizations (FAQ)

In order to learn how to use Firefox efficiently you should become familiar with using HELP (F1), shortcuts, and menu items as a starting point.

The main difference people used to experience with Firefox was Firefox has tabs, today all browsers have tabs, but Firefox remains the most user customizable browser.

Firefox after Internet Explorer   (#intro)

Firefox web browser, my notes on setting up and customizing Firefox with selected extensions after having used Internet Explorer.

Have been using Internet Explorer for several years, and wanted to have more flexibility using Mozilla Firefox which offers more robust bookmarklets (IE limited size), better Ad Blocking (project) to block banner ads and block popups.  Now "Adblock Plus" with EasyList Subscription are used to block ads and block popups.  The initial frustration with Firefox was not being able to easily get into an editor like Notepad (see Notepad link below), and in not being able to copy the link and title to paste into source as an href anchor (see Copyurl Plus, and Multiple Tab Handler below). 

Something probably unique to my site is the page on use of Right Click menus in Firefox, which are properly called Context Menus because the menu changes depending on where you right-click.

FF Titlebar

Menus, Search Bar and Firefox Throbber   (#searchbar_menus)
FF Menubar

Search Menu
Search Menu

Searchbar:  The Searchbar (defaults to Google search engine) that comes with Firefox is too SMALL and Narrow.  (BTW, move the Search Toolbar to end of Firefox menus).  Solution: see Change the width of the searchbar (400 pixels and is self adjusting) in userChrome.css but first read about creating keyword shortcuts for your profile and chrome directories to help you locate the chrome directory for modifications.  Why anyone would want to install an extension to do the same thing is beyond me -- incidentally the search bar will expand automatically in Firefox 2.0, leaving one to wonder what would happen if it is on the same row as the location bar which also expands, since there is no relative percentage maximums.

The search bar that comes with Firefox has a drop down that can easily be customized to add additional or delete (uninstall) search engines (Mycroft).  Do not bother with the Googlebar extension, it is not needed, and the Mycroft customized search engine additions provide far more flexibility.   For a picture of my actual search drop down click here, or see a different example.  For the Advanced Search for Mycroft Search Engines, Mycroft Project: Sherlock & OpenSearch Search Engine Plugins

Menus & Tabbed Browsing:  Ctrl+T, bottom of folder in directories/links has “Open in Tabs” -->

The Throbber can be changed to address additional home pages with up to four pages with the "Throbber Button" extension.

Location Bar 

FF Location Bar

Use icons without text on most toolbars.   New Tab button comes with Firefox, but is enhanced with Drag and Drop extension which has been built-in since Firefox 1.5.   You could use Ctrl+click on a link instead of drag and drop.  The Launchy extension provides the ability to invoke Notepad, installed browsers such as IE or Opera, the Windows Explorer, or a choice among text or HTML editors.

At the right end I have Open a New Tab to facilitate use of Drag to Tab, and the Launchy icon as a time saver alternative to having to use a secondary menu within the context menu.

Suggest you continue reading below for problems, adaptations and customized implementations now; and, use the links at the top of this page later for more detailed usage of Menus, Toolbars & Context menus.

Plug-ins   (#plugins)

Plug-ins:  (Firefox list of popular plugins – For a more complete list see bottom of that page, and check specifically for your system ).  Be careful where you obtain plug-ins from -- the pages listed on that page would be the right places to use. 
  -- PluginDoc: Windows (Most Popular))
  -- PluginDoc: Windows (A - Z), Mozilla Plugin Support on Microsoft Windows
Adobe Reader:  PDF files should be directly opened with the Acrobat Reader (.pdf file type), never allow browsers to open them.
Java Plug-in -- Most users should be at Java 6 for more information see automatic update warning to check out your Java plug-in (Important !!!)

Diagnosing plug-in problems

To find what plug-ins are installed type about:plugins into the location bar.  Read topics within

The Infolister give you a nice listing of installed extensions, plug-ins, and themes.  You can compare your list to mine to make sure your versions are at least as high as mine, see my /example/ though most don't actually show the version there.

This is what I have for my actual listing for about:plugins you can check the date I created file by looking at the directory that the Plug-ins.htm is in (using Windows 2000). 

Change plug-ins location: - Mozilla - Plug-ins with Mozilla, also see Move plugins to another location - Firefox - MozillaZine Knowledge Base which may describe other locations that would be found.

Themes   (#themes)

As mentioned at the beginning, I'm not into themes, but you can see what themes you have with Tools, Themes and you can obtain theme add-ons at Themes: Firefox add-ons or you can build your own search engine for themes see ...

Firefox Notes  (#firefox) Mozilla

IE View (Firefox extension, right-click) will bring up Internet Explorer window of same name.  (#ieview_topic)
As popular as IEView is, Launchy does so much more and if you install Launchy then IEView becomes redundant.
Firefox View (available where Firefox extensions are available, right-click) will bring up Firefox window (#firefoxview_topic)
of same name from Internet Explorer. 

Install CopyURL_plus text editor extension (#copyurl_notes)

Creation of <a href=""></a>     (install CopyURL plus text editor extension, right-click(#copyurl)

based on additions to user created user.js file within the profile folder,
More information in copyurlplus.htm
Example output of built-in Plain Text choices
Specific short example

 (4) Copy URL + <a href=...>...</a>, selection
 (5) Convert TEXT to HTML code
 (6) DIV Offset + <a href=...>...</a>, selection
The CopyURL+ extension for copying and pasting the link title, and url from the line anchor information, along with the current selection, is easily customized to format this information using patterns of your choice to paste into other applications.  Some suggested customization patterns are included for blogging, HTML, plain text for email, and other uses have been provided.

There are 3 built-in menu items that you may or may not see depending on what is selected,
and whether you RightClick on a link or not.  Forward slashes in display represent new line. 

B1:  Title/url -- available, even if url has no Title
B2:  Selection/url -- available if there is a selection
B3:  Title/selection/url -- available if there is a selection

CopyURL+ Additions to user  (#copyurlplus_additions)

The following items are included within user.js in my Firefox profile directory for my customization of CopyURL Plus.
user_pref("copyurlplus.menus.1.copy"," <dt><b>%TITLE_HTMLIFIED%</b>,</dt>\n<dd>%SEL_HTMLIFIED%\n<br><a href=\"%URL_HTMLIFIED%\">%URL_HTMLIFIED%</a> </dd>\n");
user_pref("copyurlplus.menus.1.label", "Copy URL + <dt>title<dd>selection / url");
user_pref("copyurlplus.menus.2.copy", "<a href=\"%URL_HTMLIFIED%\">%TITLE_HTMLIFIED%</a>");
user_pref("copyurlplus.menus.2.label", "Copy URL + <a href=...>...</a>");
user_pref("copyurlplus.menus.3.copy", "<a href=\"%URL%\">title=\"%SEL_HTMLIFIED%\" >%TITLE_HTMLIFIED%</a>");
user_pref("copyurlplus.menus.3.label", "Copy URL + <a href=... title=selection>...</a>");
user_pref("copyurlplus.menus.4.copy", "<a href=\"%URL_HTMLIFIED%\">%TITLE_HTMLIFIED%</a>,>%SEL_HTMLIFIED%");
user_pref("copyurlplus.menus.4.label", "Copy URL + <a href=...>...</a>, selection");
user_pref("copyurlplus.menus.5.copy", "%SEL_HTMLIFIED%\n\n");
user_pref("copyurlplus.menus.5.label", "Convert TEXT to HTML code");
user_pref("copyurlplus.menus.6.copy", "<div class=\"offset\"><a href=\"%URL_HTMLIFIED%\">%TITLE_HTMLIFIED%</a>, %SEL_HTMLIFIED%</div class=\"offset\">\n\n");
user_pref("copyurlplus.menus.6.label", "DIV URL + <a href=...>...</a>,selection");

The additions: 1) is a dictionary list entry, 2) is the basic HTML link, 3) HTML link selection internal, 4) HTML link selection external as comment, 5) will create HTML code from text, 6) will create an offset listing if you install the required style.  There is no check when presenting the additions that you have a selection or that the cursor is on a link.

If you end up with doubled set of options, see doubled problems on my page which provides more extensive notes on COPYURL Plus, create a link for HTML

Launchy Notes , opening Notepad and other applications (#launchy_notes)

Launchy will launch a program, or editor from a webpage or a link.  The Notepad editor is included in Launchy context submenus, providing sought after ability to edit with Notepad when using Firefox.  I wanted to also include HTML-Kit and Edit Pad Lite.  Since it is more difficult to click on a submenu item, suggest installing the Launchy toolbar as well.
Launchy (Context menu)

Launchy Links context menu

The following code goes into the launchy.xml file that you create in your chrome directory (see customizations), per instructions in     Launchy will look for a file called launchy.xml in the chrome directory in your profile

(If you are bothered by words running through tables, especially on low resolution monitors, see write-up with Toggle Word Wrap).
<?xml version="1.0" encoding="UTF-8"?>
<configurations xmlns="">
    <label>Edit Pad Lite</label>
    <command>C:\program files\JGsoft\EditPadLite\editpad.exe
    <label>MS Front Page</label>
    <command>%ProgramFiles%\Microsoft Office
    <label>Windows Explorer *1</label>
For a sample launchy.xml to be able to bring up more browsers, and to be able to bring up other Firefox profiles with other versions of Firefox, see example launchy.xml.

Before adding anything to launchy.xml use Tools/extensions select Launchy and check the options list.  Even though Windows Explorer should work as File Explorers (type 6) from options, I had to add it to browsers (type 1) for it to work for me to look at directories and to verify an extension is opening in it's default (opened bug 8874).  Although not shown I did find value in also adding NOTEPAD to extensions (type 1) so that you can get to notepad from a link, not recommended for others because a fragment-id would mess up direct usage.

With the above XML for Launchy in place, I get the additional context menus in Firefox that I wanted and basically the results I want and need to use the Windows Explorer, not to be confused with Internet Explorer. 

  1. A link of the form will fail in Launchy with “The path '8874' does not exist or is not a directory” -- an error message, but quite tolerable and understandable as there is no file extension.  [right click on the above link, choose Launchy then choose Open link in Windows Explorer *1]
  2. A link of the form will open just fine in the default browser and is needed and lets me know if my default browser is properly defined and working.  [right click on the above link, choose Launchy then choose Open Link in Windows Explorer *1]
  3. Open a link to a local directory such as file:///c:/temp/ in Firefox, then right-click on white space (non link) then from Launchy bring up Windows Explorer.  [left-click to open link, then right click within the browser's directory view to bring up Launchy then Open in Windows Explorer *1]
    The additional entry for Windows Explorer is needed to open said directory with Windows Explorer from within HTML.
  4. Don't open the link from the browser but use the Launchy context menu to open the link to a local directory such as file:///c:/temp/ [right click on the above link and choose Open link in Windows Explorer *1 or from the Launchy default Browse link in Explorer.
    In the case of Open Link there actually is no need for the additional XML definition, though I personally like it as a choice with the browsers even if duplicated.
  5. A link to a .jpg file such as ../icons/ff_launchy_irfanview.jpg opens according to it's file type and lets me know that it is properly defined and working, and more to the point lets me bring it up in it's intended application without additional definitions for Launchy.  [right click on the above link, choose Launchy then choose View Image in IrfanView]
  6. Place cursor anywhere but a picture or a link on this page, using Launchy this page should reopen this page in the default browser.  [right click on the above link and choose Open in Windows Explorer *1]

Don't worry too much about the type, you will see how they group from the above examples.  Within their group the items are alphabetical.

To help create a Launchy entry use file search to find the directory, if you have a problem it could be you have more than one, or you can't simply use something like frontpg.exe as you could from the Run program dialog.

If you have installed IrfanView (and have .jpg defaulting to IrfanView) you can read the Exif Data information recorded by digital cameras or photo retouching by right-clicking on the picture, choose Launchy, then IrfanView, use shortcut character “I” to see picture information.  [notes on IrfanView]

Webdings and wingdings Fonts can no longer be made available in Firefox   (#wingdings)

Customizations to support Windings and webdings is no longer supported in any manner as of Firefox 3, so this section has been archived.  Web authors are expected to use Unicode to be compatible with all browsers and all systems.  You will find some of the more common unicode symbols on my Symbols page.  (You are expected to someday have an up to date computer to handle unicode characters in various fonts.)

If the page is coded with older wingding and webdings, you will have to use Internet Explorer (possibly an older version), and if you are the author of the document, update to using unicode. This problem may affect use of barcodes as well, you will have to check barcode documentation to find out how to include your fonts.

Notepad  (#notepad)

Not having an automatic tie in to Notepad for View Source, can be alleviated by any of the following: If you change your default editor, you can still view the source of a webpage from the location bar as follows:  [ref(1), ref(2)]

Default Browser  (#defaultbrowser)

default browser — it doesn't really matter.
Though Firefox is now my default browser, I had continued with IE as the default just in case it made a difference, as it does on the Microsoft update sites.  Was perfectly happy that Firefox was invoked from links in Outlook Express which was all that really mattered to me – perhaps because Firefox was installed later.– You've normally decided which browser you want to use by selecting that icon from your Quick Launch or from the desktop, but Launchy provides the means to bring up any additional installed browser looking at the same page you have up from within Firefox, and other versions of Firefox with various profiles.

folder options, files types... and Windows Explorer, because I have added Explorer to the list of browsers within the launchy.xml , it is easy to remove the filename portion of a URL at the location bar to get to the directory listing (on your local drive, and some websites) then to use Launchy to invoke Explorer which since it is a directory brings up Explorer listing.  Columns in the directory not normally seen in a default Windows directory have been included via View, Choose Columns.  The Comments column is used by Excel.  You might choose different or additional columns for other directories.  Directions to make Firefox your default browser.

Firefox EXTENSIONS (#extensions)

What are extensions (#what)

Extensions (documentation):  are small add-ons that add new functionality.  They can add anything from a toolbar button to a completely new feature.

Customizing your Firefox with add-ons, some documentation with loads of pictures for novice users, currently in initial development by Mozilla Support Planning.

Where to get extensions (#where)

Firefox Extensions (, approx 89 433 1,000 extensions listed for Windows, this is the ultimate destination after being tested for fitness.  (since the search reports exactly 1,000 it is probably a limit of results it will show and no longer accurate) The “More Information” and “Home Page” links normally link to a group page like or to the extension author's own page(s).  Has Popular and newest categories.

compatible:  Whether you look at all of the extensions (1848 Window extensions) or from a search you probably want to look at 100 at a time.  On the Extensions page there is a search form, use the form for any search then on the results page there is a "Show Options" to the right of the search form which can be used to specify your own defaults for a search, which you can use to create a search engine...
Create an engine for the searchbar to search for the Extensions by right clicking within the search form (with all default options).  In order to accomplish this you will need to install the Add to Search Bar extension.

Extension Room ( approx. 225 entries (before Firefox 1.5), where authors provide their approved submissions.  Currently shows 120 extensions but not that are shown are available in Firefox 1.5.  You can see them there all at once.  Topics on the sidebar include:  Active ProjectsExternal ProjectsProject Categories

The latest versions are often on the author's own web pages:  particularly when a new version of Firefox comes out.  The authors websites, if available, have been included in the table below.

Install this as a keyword shortcut ext: search extensions -- add-ons extensionroom add the ext: shortcut to the properties.

If you can't find a Firefox extension, you might still find a bookmarklet or favelet with bmk: search bookmarklet OR favelet add a keyword shortcut (kws.htm) to the bookmark's properties as "bmk:" if you want to keep that as a shortcut.  A very large collection of bookmarklets described on the kws.htm page can be found as exported bookmarks in k.html

If you want to double-check for additional extensions after you have installed extension first from then you might recheck by looking at active projects at, which can be sorted by name or by date.  You can also look at the FAQ and other topics from the left side frame for some orientation on projects and extensions from the developers (code writers) perspective.

The table of installed extensions on the right can be created by Listzilla or Infolister.   Descriptions (Title=) can be seen if you hover over the links.   The Listzilla listing is not automatically updated; however, an up to date listing of my actual extensions in use can be found in my /Infolister/ Ext. listing, which is included whenever my site is updated..     

Late modifications:  Just because I disable or eliminate an extension does not mean it was a bad extension.  I have very limited RAM memory and too much page swapping, if an extension has lots of features takes a lot of overhead and I only want one feature, it will probably get removed, and may be reinstalled on a bigger machine.  removals: Clone Window, Compact Menu, and googlebar (there is a much better one built-in to Firefox).  Retaining for now:  keeping (/these) for awhile:  EditCSS (keeping even though it is in the Developer). 

Some ideas of what others feel are important for extensions.  May check these again from time to time, but I've installed those I really need, and avoid those that might be somewhat nice but are large.  Of 54 currently enabled extension, only 14 of those are over 34KB installation size.

Installing an Extension   (#install_ext)

To allow software to be installed you must have:  Tools, options, Web Features (left side in earlier versions) or Content (top) in Firefox 1.5, [x] allow websites to install  software.  (I think there may be no more need to turn off this option as Firefox 1.0 and later will check that the file extension or download is from “trusted sites” that you can change on the link inserted when you get a conflict and refusal to install. 

 *  To protect your computer, Firefox prevented this site ( from installing software on your computer.  Edit Options

The first time you attempt to install an Extension from a site you will get the above warning, to proceed, click on the Edit Option, then inside on Allow, then reselect the extension to be installed, and it should then install.  Do not install an extension you are suspicious of, most extensions you will ever use are from the one of the four locations listed earlier. 

If you have trouble installing your chosen extensions then read more detailed Mozilla Firefox Extensions installation as described in “An introduction to Mozilla Firefox, part 4”.

For URIID at, I had to install the downloaded file by opening c:\download_win2000\uriid.xpi on the Firefox location bar as it would not install by simply clicking on the link.

I specifically will not install the Google Toolbar (extension) as the built-in searchbar is much better and is CustomizableA Race to the Bottom - Privacy Ranking of Internet Service Companies places Google at the bottom of the ranking.  (letter to Google on Data Protection Policy (not the worst on openess)

Below is a list of Firefox Extensions I have installed and still use most of them.   Most of these extensions are invoked from the Context Menu, see Firefox Right Click menus for the original built-in Firefox Context menus plus some of the additional menus items added by my own selection of Firefox Extensions.   Some extensions are installed in the tools menu, and some have optional toolbar buttons. 

Multiple profiles: is one way of essentially turning off all extensions so you can test w/o or with only one extension – Firefox Help: How To Manage Profiles, Multiple profiles and profile management is an advanced feature, mainly intended for developers.  Unless you are an extension developer or an advanced user, you should probably not be trying to use multiple profiles.

Many of the extensions have additional customizable options, all have disable/enable, more information (about ...), and update, which you can see by right clicking on the extension as found in the listing found with Tools, Addons or on the Find Updates button at the bottom of the Extensions list.

Extensions can be invoked in many different ways so I have tried to identify where you invoke them from, such as from the right-click (context menu), Tools menu, Edit menu, View menu, and even the History menu(Go menu).  Options are usually set in the Extension list (Tools, Add-ons, select ext, options), but some are in the menus just mentioned.

Adblock Plus * 2.2.2

Wladimir Palant(ABP) Eliminates ads.  Ads, particularly third party ads, are a primary source of malware and viruses.  Eliminating ads helps \\ABP// protect your system, speeds up downloads, and helps protect your system.  (video overview).  Filters are required (EasyList is recommended).  Features: Easy to add customized filter and whitelist items.  You can maintain several independent filter lists/subscriptions concurrently plus your own added filters.  [Options] [Button click/context].  Also install companion " Element Hiding Helper for Adblock Plus" (below)
Due to a change in ABP you must now Uncheck "Allow non-intrusive advertising" in the preferences to receive full benefits, and besides subscribing to EasyList, and Fan boys, you might want need to also subscribe to EasyPrivacy. The menus in preferences were moved to the right hand side.
On your Android get Adblock Plus directly from, it is not available at the Play store [ref], and it is works with Android itself so protects you on all browsers there not just Firefox.
Add Bookmark Here ² 17.0.20121128
(65.6 KB)
yuoo2kAdd a menuitem "Add Bookmark Here..." to Bookmark folders.   Must be done from within a bookmarks folder.  (related OpenBook)
The extension has additional features as well and incorporates most of the "OpenBook" extension except for the ability to expand the Bookmark dialog horizontally.  (cannot use both extensions at same time). [filledstar] [star]

There is a somewhat hidden feature as well, by right-clicking on the "bookmark here" in the bookmarks context menu you can bookmark all of the tabs to the folder (or select a different folder, or create a new folder).  Not sure what features I changed from defaults but I use Expanded, and I display all in dialog (Name, Location, keyword, description, load in sidebar) except for tags (which show up anyway, even though not wanted).  Also see Style 9029.
[Options] used see addbookmarkhere2.txt
Problem with bookmark star (edit this bookmark) appears to be with other extensions, see Bookmark Star (Ctrl+D).
New option to use folder to add a tag to bookmark could have a serious impact (IMO), esp. if intent is not to show or use tags at all.

MIKES KASZMÁN IstvánAutomatically opens a customized popup menu when you select text.  A welcome extension when you have a LOT of items in your Main Context menu even after using Menu Editor.  I like the concept but I cannot customize it by simply a context menu item of my choice (for instance first extensions that comes to mind is "Copy URL plus", and "Linky" both happen to have groups)  Interferes with Web Developer Ctrl+Shift+F to examine fonts even if disabled at the status bar.

BarTab 2.0

Philipp von Weitershausen
BarTab can intercept when tabs are loaded in the background or restored after a browser restart and will only load the content when the tab is actually visited. [ref].  Also set about:config  value of media.autoplay.enabled to false, and "Stop Autoplay".  Option to not load restored.
media.autoplay.enabled   user set   boolean   False

see Load Tabs Progressively, Load tabs one by one.  Limit the number of concurrent loading tabs and/or unread loaded tabs.
BarTab Lite 1.2
Philipp von Weitershausen
Like BarTab for Firefox 3.x, but with less features. This just keeps your tabs from loading (via the now built-in hook in Firefox) and styles the not yet loaded tabs in the manner (??)familiar(??) to BarTab users.
Better Gmail (uninstalled)(1.0)
Gina TrapaniA comprehensive suite of Gmail enhancements, including skins, saved searches, keyboard macros, secure access, attachment icons, attachment reminders, label colors, signature floating and more.  You will not see what account you are using so you might want to install a bookmark for with a keyword shortcut of "gmail:".  tested works, but not what I want for my own email.
BlockSite 1.0.3
(16.4 KB)
Erik van Kempen $$ blocks websites  This link is blocked of your choice.  Additionally, this extension will disable all hyperlinks to these websites, by just displaying the link text without the clicking functionality.  Will show tooltip of "This link is blocked" instead of title.  Status bar will not show link address beyond "#", if present, for such links.  You will probably have to restart Firefox for changes to take effect rather than just using the add-on's options to enable/disable.

Bookmarks Scrollbar (disabled/problem) 1.0.5
jAgx Andrew
Was a nice extension but Firefox 2.0 changes to tabs ruined the extension by placing a horizontal scrollbar over the tabs when using this extension and 22 or more tabs; however, you can do this yourself with simple userChrome changes see Scroll Bars.
Bookmark Sorting (works in Fx2)

For Fx3, see Bookmark Sorting in Fx3 (below).

David Lechnyr
There is was an excellent extension written by a guy named Torisugari called, simply enough, Sort Bookmarks, but was never updated. This is an updated/enhanced version.  Sorts your bookmarks.html,   Adds “Sort by Name” to the Bookmarks menu (or perhaps your default sort).  [Tools]  [related: bookmarks manager] Note to form a group for sorting purposes you must use two separators before and after the group or so I think I'm told.  Says it works with Fx3 (Places) as well which will be a database instead of an HTML file.  Fx 3.0b2 has sort built-in see next topic. || of interest Bookmark Sync and Sort, if modified to handle Fx3 bookmarks.
Bookmark Sorting in Fx3

(for Fx2 see previous topic)

Sorting of bookmarks is built-in to FF 3, context menu ("Sort by Name") is used on the individual folder and is NOT recursive for subdirectories.  You can't sort on the overall "All Bookmarks", but you can sort from each of it's subfolders in 'Places Organizer' (Ctrl+Shift+B) and in Bookmarks (Ctrl+B): "Bookmarks Toolbar", "Bookmarks Menu", and "unfiled Bookmarks".  You must now select the folder not a file within a folder in order to sort.  Bookmark separators cause groups within folder to be sorted within each group.  Recursive sorting has not been included.

To sort bookmark folders recursively, see SortPlaces .  To quickly access Library list from a bookmark folder recommend also installing Manage Folders .

The "Library List" (invoked from Bookmarks, "Organize Bookmarks") has an additional sort ordering from the Views menu.  Views also specifies which columns will be seen, but is not sticky you have to choose your non default columns each time. 
Bookmark Star [star] [filledstar]

benki (orig) 0.8
GUI Front-end to listcache entries of "about:cache" [2].  Allows searching on parts of the urlnames(key column) with one or more strings in any order (i.e. ".org /icons/ .gif") and sorting on any of the columns.  i.e. filter on JPG then sort on time, use down arrow to browse through the files.  You can see additional columns by clicking on little icon to right of rightmost column header.  The key column is the urlname, the selectable columns are:  *mime type, *size, *Device, *Last Fetched, Last Modified, Expiration Time, Fetch Count.  You can rearrange columns.  Display rows have a context menu to browse, save, or delete.  Double-click the row to view the file in browser.  You will not see local files in Cache Viewer.  [Tools][F5] (Cache contains even more... Web Browser Forensics)
usage tip:  Use search as filter to narrow down to domain or webpage and/or word "image" then use of the down arrow key to view each next cache image, very fast because it is all in cache.

Loss of icons on search results even though Customize Google has "show icons for web pages" will be lost when signed into Google.  Experiment with combinations so that you see the actual icon of sites and not Google icon for all results or no icons.  If you do not see the icons you will not see the important replacement icon on the left, (!) advising of an attack site [ref].  Google adds the warning "This site may harm your computer" which is easy to miss, fortunately Firefox itself will block such sites (Tools, Options, Security, [x] block reported attack sites).  (see style 16887, incorporating part into style 16842).
Being signed into Google will mess up Google searchs, especially if using "Customize Google", so there are some additional features to be used from Google Enhancer instead of same feature in Customize Google.

Easy Copy2.7.0 (46.6 kB)Byron Copy links to a page with one click, ready to paste anywhere else, eg. emails, blogs, forums and Twitter. Copy a single page, all open tabs or all links on a page.  Adds "Copy All Tabs ►", "Easy Copy ►", and "Copy Title Link" to the main context menu.  You can process the active tab or all tabs, but unlike Multiple Tab Handler you cannot be more selective of which tabs to process.
Features:  (HTML below means rich-text format ready for pasting)
* Copy links to a page with one click, ready to paste anywhere else.
* Copy other details such as its URL, title, today's date, HTML source, etc.
* Lots of pre-built templates including copy title as link, Wiki-format links, BBCode links, HTML Source and more.
* Copy across all tabs in the active window or all windows. See the Copy All Tabs Options.
* Copy all links on a page or links in the current selection.
* Copy selected text as plain text or Markdown links. See More Template Ideas for details.
* Move frequently-used templates to the main context menu so they're one click away.
* Assign keyboard shortcuts to frequently used templates. Note: Keyconfig is required if you want to manage shortcuts.(addons: Keyconfig
* Create your own templates with lots of variables to choose from.
Also see Multiple Tab Handler, which I prefer, even though would have to use an online HTML editor to create rich-text-format.

(You may have come here looking for Find Problem).  Firefox 3 has incorporated "Highlight All" into the Find bar (you can modify appearance with style 7566), so if you use it first then Find it will work very much like Opera.  Also check out "Context Highlight" extension if you want to have more than one choice highlighted such as "Firefox" and "JavaScript".

Warning & Disclaimer: Firebug is obsolete and no longer available see Firebug Alternatives: 10 Best JavaScript Debugging Tools.  As far as I am concerned Firefox was destroyed by graduate students who essentially said nobody needs lots of bookmarks, hardly anybody uses bookmarklets, nobody needs descriptions in their bookmarks, tags are the same as keywords, nobody needs the browser as they want it anymore, nobody needs to crunch down wasted space in their toolbars or make them more usable.  The use of user styling was rendered useless.  Mozilla chose not to pay attention to their users.  There is no decent browser anymore, Firefox self-destructed.  Firefox Problems & Issues (Notes).  This page will only receive minor maintenance, and no corrections for bad links, most of the extensions do not work - a tribute to self-destruction.  If you still want to use Firefox or Chrome see Bookmarklets, history, exported bookmarks, extensions for Chrome & Firefox.  The small laptop I was using for post Firefox 56.0.2 was rendered unusable by a Windows update.

[Button]  The bookmark listing is ordered alphabetically in a case-sensitive way. Filters match against bookmark name or keyword [should not be as keywords are not case-sensitive].  There is a similar extension by Cory Schmidt, working on pre-Places Firefox versions named KeywordBar (above), which I liked better as it worked from a shortcut.

Severe weather warning!  Nightly Tester Tools 2.0 tries to take over compatibility, reply NO to retain documented versioning, or lose forever until the next Firefox update this vital information as related in addons list (read comments 2008-04-24 in author's page).
After a browser update, NTT will "disable" a lot of extensions, even though you have extensions.checkCompatibility set to False, since you would not want to lose the exclamation warning to re-enable extension, you can get things back to normal by disabling NTT, restart Firefox, see your extensions are back, and then re-enable NTT.  I could probably do with just the Title bar information and do away with everything else just to do away with the disabling nonsense.

Phoglenix Enhances the Google search results by adding extra information on WEB searches (like links to Yahoo, Ask Jeeves, MSN etc) and removing unwanted information (like ads, and spammy sites) with a filter.  All features are optional and easily configured from the options menu.  Helpful in overriding Google cookies should they get changed.  The streaming option allows you to effectively have more than the 100 max hits, by allowing you to scroll past the limit to pick up more items.  [1] [2] [3] [4]
Works only from Google toolbar, or using a keyword shortcut not from search box at Google.
Differences between a signed in Google user and an unsigned in Google user, as seen at the top of the search results necessitates additional use of another extension GoogleEnhancer
  Options to set only in CG -- streaming (not position counter, nor show favicons)
  Options to set only in GE -- Load results favicons, Number Results Nevertheless, being signed in to Google really slows search down, and prevents CG streaming(next pages) for getting additional results at the bottom, and challenges you as being human -- so you really should sign out of Google when doing searches.
A recent change (0.52) hides the suppressed urls, to see them again you will need to show the title with the mouse or with a bookmarklet paren tips
Suggested options: Remove ads, Add position counter, Remove click tracking
Loss of icons on search results even though Customize Google has "show icons for web pages" will be lost when signed into Google.  Experiment with combinations so that you see the actual icon of sites and not Google icon for all results or no icons.  If you do not see the icons you will not see the important replacement icon on the left, (!) advising of an attack site [ref].  Google adds the warning "This site may harm your computer" which is easy to miss, fortunately Firefox itself will block such sites (Tools, Options, Security, [x] block reported attack sites).  (see style 16887, incorporating part into style 16842).
Being signed into Google will mess up Google searchs, especially if using "Customize Google", so there are some additional features to be used from Google Enhancer instead of same feature in Customize Google.

PermaTabs (12KB) [Fx2] by David Morrison

turn tabs of your choice into permanent tabs(Alt+P).  PermaTabs can't be closed accidentally, remain locked between sessions, and by default force links within to open in a new tab.  Perfect for doing a links check.  Can be optioned to be like Opera's Lock Tab.  [options] [tab context].  Reload (F5), Back, Forward, and bookmarklets work okay.  /jpg/ Appears to be available only for the first instance (Window) of Firefox in the system status bar.  My userChrome changes had prevented me from seeing tab color changed to yellow -- so was only apparent in tab context menu, but if you use my userstyle 9023 you avoid conflicts with coloring of Flat tabs.  While tab is protected cannot use bookmarklet (href:) within tab;  Usage Examples:  Protect page while checking out links with Checky extension, protecting a page while listening to a podcast.
Did not work and menus were not seen when Menu Editor was enabled, although they did work together on another fx 3.0.8 profile.  With both enabled these steps may or may not be complete but both are working now. Rebuilt localstore.rdf (reduced from 61.8KB to 7KB, but no change), dragged toolbar button to toolbar and clicked, works, turned grouped options of ext back off in Menu Editor, removed toolbar button from toolbars. Still working together. Seems the single context option only works for a session, only the context folder like option carries into another session. (related topics: tabs)
[Fx4] Firefox 4.0 introduced app-tabs which will force links to open in a new tab, which is the primary benefit to me of Perm Tabs Mod, you may have to use Perm Tabs mod in 4.0 instead, looks like there would be a lot of rewriting of the enxtension with little benefit, for myself I would only have one such tab being used such as for checking for links to having a constant width tab at the left for that purpose is about how I work with a permanent or locked tab anyway.

Scott R.  Turner Lets you modify a Web page from your browser -- "What You See Is What You Get" -- and then save those changes as a Greasemonkey script so that they'll be repeated the next time you visit the page.

Once installed, please read the Platypus help page [chrome://platypus/content/help.htm], or hit the '?' key after starting Platypus, if you are confused about what Platypus does or how it works.  This 404 page is a good page to test with (or this more extreme example of bad layout).  Start from context menu, use Ctrl+X (Cut) to remove portions, use I (Isolate) to isolate and keep only what is selected, use P for Page background removals, use S (Style) to modify font, use R (Relax) to remove width restrictions, and finally Ctrl+S to save in Greasemonkey (you will then have to use the pop-up or tab to install the script). Went from 67KB to 209KB download for what is marked as "minor" changes for Fx3 usage, and still no undo.

Adds a toolbar button (toggles) and Ctrl+Shift+Z to make hard to read sites readable by removing gaudy CSS usage, as a faster alternative to using View menu, Web Developer, or bookmarklets.  Both Firefox and Opera have built-in simplified style choices and user customization of styles under the Style Menu.  The toggling of icon lets you see if extension is invoked or not.

Suggest you do not have SortPlaces invoke sort automatically via it's options, use the statusbar or toolbar button, or bookmarks menu instead to sort.
SortPlaces or built-in sort will result in destroyed bookmarks and folders if you have BookmarkDD installed -- uninstall BookmarkDD immediately whether or not you install SortPlaces.

in order to regain
features lost in vers 1.*.*

1.3.1 (269.1kb)

Jason Barnabe (np)

Customize the look of the application and of websites with Stylish, a user styles manager.  Make Firefox 3 and Firefox 4 appearance usable with slimmer toolbars.  Unlike other methods of using user styles, most styles take effect immediately.  [Options][Help] [discussion]. (Styles I wrote and the styles I use)
Warning:  You must now install 1.0.*, the important thing is to be able to install styles. Version 1.0.* is a disappointment, it jumps the shark, has a very bad user interface. Hopefully an update someday will put it back see discussion [2700].  Lost ability to add !important, lost ability to use a color picker to change/insert color.  Syntax checking is probably impaired. Illogical placements of buttons. Loss of checkmarks to show style is ON/OFF, which is replaced by a style that shows half as many styles in the same space with horrible new stylish icon, horizontal bar, and bold/normal text, and loss of columns which also had standard sortable conventions on the column headers themselves.  Where 33 styles could be displayed now only 15 can be seen, so what took 2 views now requires 5 views to see styles.  To regain some of the simplicity before Stylish 1.0 you have to install Stylish - Manage Window beautified (style 17571) which is tacky but at least shows one more column than 1.0 by itself.  Another extension to fix an extension by the one person who praised the Stylish 1.0, adds stuff back but has lost the quick interface and simple style of the original -- Stylish-Custom (addon 12105).  Also see style 17866, style 17975 -- none of the extensions alone or altogether can put Stylish back together again.  Be sure to change extensions.stylish.manageView to 1 instead of 0 so it doesn't mess up view of addons.
Styles, and Extensions: that is use and refer to can be found in User:Dmcritchie (MozillaZine).  In addition bookmarks (links) for Styles, Extensions, keyword shortcuts, and documentation: that I use can be found in my exported bookmarks file (k.html) that you can read as HTML or import and move the folders to your bookmarks toolbar (see Directions to install k.html bookmarks and keyword shortcut usage articles).

Useless Extensions  (#moreuseless)

I consider the following extensions some of which may be very popular to be useless or prone to trouble for reasons set forth in the previous topic.  If you personally know the author or are very much on the same wavelength then they may be good for you, but I think they try to put too much into their extension and you can do much better with a few much smaller extensions or preference options that do exactly what you want.  Also be aware that if part of a massive do everything extension breaks the entire thing may be broken.

More Extensions * (#moreext)

I think you will find most of the useful extensions on this page, and you've seen above what I want in extensions and what I don't want and consider useless, now you can make your own choices, by searching for additional Firefox extensions as follows:
 Mozilla purposely eliminated it's Advanced Search (bug 372841 - 2007-03-06 - Bring back the advanced search options from v2 to Remora [Fx].).  Unfortunately this is triaged with bugs that do not make a bit of difference to me because I want to specify exactly what my system needs are and use it in my own keyword search or on my own search engine as created with Firefox or with "Add to Search Engine" extension.  Losing this ability for over two years is inexcuseable, but then the entire add-ons site has rapidly gone downhill with its offensive GUI styling.  Advanced Search has been restored (bug: 372841) in June 2008 a bit more limited but it is now at least available/accessible on each AMO page, and you can once again tie into it with your own keyword search or search engine.  Also see key word search page for "addons:" search so you can use the full power of Google to search AMO. 

Add a Customized Search Engine to FIND Extensions at * – Important!!!    (#customsearch)

To install your own engine after installing the Add to Search Bar extension, click here to invoke a sort with no results [if link at left is still broken then click here for old search], then set up the “Advanced Options”, my suggestions are as follows: 
  Category: any, Type: Extensions, App: Firefox, Platform: Windows,    Date: Any,  Sort by: Newest Name, Per Page: 50

When finished with your settings, right click in the search form at the left of the search button and chose the Add to Search Bar.  Both “Add to Search Bar” and “Add a Keyword for this Search” were added to the context menu with the Add to Search Bar extension. 

When using your new search engine for extensions at addons, you should be aware that it is not like a Google search and works best with a single word or with the exact name of an extension for the search argument.  I like it because you can read about each extension found and click on the link for the extension to see user comments and additional information such as download size.  The search used appears to be rather primitive compared to modern search engines and requires that the search arguments should be in alphabetical order (2006-12-04).  Examples:

context (192), color (39), color context (2), context color (1), toolbar color (6), color toolbar (5), shortcuts (27), zoom (16), zoom mouse(2), mouse zoom(3)
 Mozilla purposely eliminated it's Advanced Search (bug 372841) so you can't use the above example even with the partially restored AMO Advanced Search, see 2007-06-14.

The addons site is better for add-ons but the search at for extensions actually uses a custom Google search: %3Ahttp%3A// %3A69%3BLC %3A%23990000%3BAH %3Aleft%3BS%3Ahttp%3A// %3A39adc05eb4f99617%3B&

You might also find use of a keyword shortcut (“ext:s” or “addons:”) to use Google to search at addons:    [additional improvements to addons: keyword shortcut below] +inurl%3Afirefox+install-now +-inurl%3Arecommended +-inurl%3Aphp+%S

Security in your web Browser   (#security)

Security Considerations in Firefox

Firefox 1.0 provided more inherent security than Internet Explorer 6, while both browsers have advanced a lot, you can improve your security by blocking unwanted third party advertising that makes a mockery of the privacy statements on large company sites, where they absolve themselves of many practices carried out by another company on their behalf. Some about:config items to consider, they may keep you out of sites though, so you may end up using the defaults.
  1. network.http.sendRefererHeader set to 0 (default is 2) see
  2. browser.send_pings set to False (default is True)
Some privacy concerns to keep in mind, not necessarily related to a browser.

Tools Options of Interest (#options)

Firefox 4.0 updating needed -- old for Firefox 3 as well

General:  Perfectly happy for now to NOT have Firefox check if it is the default browser, because Firefox is picking up the links from Email and postings, and leaving use of Explorer to IE.  (Firefox was the last one installed)  Done later, but Firefox is now my default browser.

Privacy: History (21 days instead of 10 my choice), Cache, Up to 20000 KB of disk space for the cache — This is a performance issue based on bug reports and should be reduced from 50000KB

Content (Web Features): turn off Java, but leave JavaScript turned on.  Looks like I have both of them on now.

Open links form other applications
    (•) in a new tab in the most recent window

[ ] Allow text to be selected with the keyboard (caret browsing, keep this off)
[x] Begin finding when you begin typing

Dial-up considerations, suggestions   (#dialup)

Firefox with it's tabbed browsing works very well with dial-up access, as you can load up several tabs from links with Ctrl+Shift+Click, or from Open all files in a folder (bookmarks) into tabs.  You can read the first tab or continue to read the first tab while other tabs are loading.  Some other things you can do to help with dial-up.

Tools, Options, Content, [x] Load Images, [x] For the originating site only.  You can also modify allowed/disallowed sites.

Adblock PlusMake: Online : Mercury "beating heart" works with gallium, too, one of options is to “Remove Ads” instead of simply hiding them (actually in development not production), supposedly this prevents them from loading in the first place.

I am no longer on dial-up, but Firefox made things a lot easier on dial-up

Web Developer can make setting options in tools and other preferences easier -- watch out for second and third level menu directories that may obscure that you've changed/disabled something.

Defeat Location bar Search (#locationbarsearch)

You have a built-in searchbar with Firefox, there is no reason to have a search start accidentally from the Location bar, when you have the search bar and the ability to use a keyword shortcut to invoke a specific/customized search from the location bar.  Some people don't mind being hijacked to a page they didn't ask to go to, but I find it annoying.  Anyway these are customizations and you choose what you want to do or don't want to do.

If you enter a non address into your Location bar in the form of multiple words you will get a “I'm feeling lucky” search, which is controlled by keyword.URL which defaults to:
and changing that seems to stop multiple word searches.  For single word entry, Firefox will insert http://www.  in front and insert a suffix of .com to the single word.  See topic:  Change the search mode in the address field in Firefox Help: Tips & Tricks again not needed, because you have shortcuts for (.com, .net, and org).  Changing the site name to will try to find the file on your machine, where it will not be found; therefore, an automatic error.  What follows is a change you can make to your preferences in user.js or using about:config on your location bar with the following change.

keyword.enabled           False  (default is True)
googlebar.searchoption    False  (Googlebar is an unwanted extension)
The unwanted default for keyword.URL is sourceid=navclient&gfns=1&q=   which can be restored with right-click then Reset.

Additional Location Bar Things  (#locationbar_things)

Bookmark Shortcuts, Keyword Shortcuts Creation and Keyboard Shortcuts   (#keywords)

Mozilla Custom Keywords, create shortcuts for your favorite search engines, and other sites.   I have mine set up for a web search, get to the chrome directory, search a few selected sites, dictionary, wiki, stock quotes -- things that can use the substitutions for the %s at the end.

Suggest putting your keyword shortcuts in their own folder.  Anything after the keyword in the location bar will replace %s in the shortcut bookmark.  My folder is named K within my Bookmarks Toolbar.  The folder doesn't have to be readily accessible for use but you want to have fairly quick access to add items to it, and to help you “remember” the shortcuts you created.  I choose to put a colon at the end of the word.  More information: SitePoint Forums - Issue #64 - Team Tips (Cont'd...)   The following may be customized for my own use but give you an idea of what you can use.

Keyword Shortcuts are one of the most important features in Firefox, and so have created a new page where you can learn more about shortcuts and how I use mine, including shortcuts to get to the Firefox Profile (profile:) directory and the Firefox chrome (chrome:) directory. 
— Proceed to my Keyword Shortcuts page

Set your home page [home], and your throbber [throbber] pages   (#homepage)

You will have to reinstate your home page choice if you reinstall Firefox. You can change the address for your home page icon (or Alt+Home) under tools, options, advanced.  You can no longer [Fx2] use a simple change to your configuration preferences to get another page on the throbber, but you can get up to four pages with the "Throbber Button" extension.   Beware of theft of your homepage, you don't want to reply to some website including Mozilla asking if you want them to be your home page.  Check using  about:config   for “home” as home page change may be temporary override.

Multiple Home Pages

You can select all tabs in the window to be used as Multiple Home pages, by separating files with an vertical pipe symbol, |, choosing Options, General, Use Current Pages, or even reference a folder of bookmarks (ref. Firefox options].  Most people would be annoyed with starting up multiple pages when a new Firefox window is started, especially since there are lots of other options available such as a folder of bookmarks possibly on the bookmarks toolbar that gives you the option of open everything in the folder, lots of extensions, lots of search engines for the Firefox search bar from Mycroft, and you can make up keyword shortcuts.

Problems with Home Pages

Unlike IE, Firefox does not have a user set lock on toolbars and home page to prevent theft of home page.  Installing a package to run on your ISP typically changes a homepage, but fortunately they usually just hit IE.  Software with a laptop designed for wireless use at different locations (work, home, travel) may change home page depending on location – i.e. ThinkVantage Access Connections installed on all ThinkPad laptops (solution).

If you provide an incorrect home page url, you will probably get the same error that you would get for any other incorrect url that is not found -- "Firefox can't find the server at"

Batch Start of Firefox (#batch)

There are several useful ways of starting Firefox in Batch, including bring up a specific page (like homepage), ability to have more than one profile in use at same time, bring up a specific profile, bring up safe mode.

User Files and Extensions in Firefox (#files)

Downloads can be seen from Tools, Downloads (Ctrl+J), and are maintained
in file:///c:/Documents and Settings/userid/My Documents/My Downloads
-- the location is actually defined in Tools, Downloads, Show Folder (button)
Extensions (installed) can be identified from Tools, Addons.  Note the buttons at the bottom: Uninstall, Update, and Options, and the link Get More Extensions.  Select an installed extension and use the Options button to change the options for a particular extension.  Use the link to check for additional extensions categorized at MozDev.  The install.log can be found the same directory that Firefox is installed in.

Changes to Web Pages (#changes)

You might want to check updates to webpage, to see changes that are made on a daily basis or other timespan.  Just so you know I update my pages frequently for very minor changes so you might not want to omit or increase the time between checking my page.

Performance   (#performance)

Do not take performance suggestions too literally, if it doesn't make sense be careful.  Reliability and recovery is more important than speeding up something that does not happen often.  A lot of the worst offenders are in the system see Windows 7 for things like turning of all indexing, autoplay, etc.

Also see Problems above, and Related below.
Some of the following include links to the executable software that I have installed on my computer and are identified as either “.exe” or /\ (so those links may not work for you).  Using Internet Explorer you would simply click on those links to invoke those programs if installed to the same directories as on my machine.  Firefox won't allow you directly run a program from a link, but you can if you invoke those links through Launchy and then Open in Windows Explorer.   You will have to have installed Launchy and have set up your launchy.xml as I have shown on my launchy_notes on this page. 

Installation and other problems covered earlier.
