Infolister Listing (Main)

http://www.mvps.org/dmcritchie/firefox/infolister_listing.htm

Compatibility testing with Firefox version has been disabled from the start of use of Firefox 2 -- see bottom of this page for how it was disabled. 

A descriptive Summary of each of the listed extensions can be found as part of my Firefox Customizations (Notes) at (#ext) [http://www.mvps.org/dmcritchie/firefox/firefox.htm#ext]

Quick Summary of my System

Old system -- Dell Inspiron 5000e

Manually entered information for OLD system Dell Inspiron 5000e (laptop), 600MHz, Pentium III, 512MB RAM (max) was upgraded from 128MB, Windows 2000, Firefox 2.0.0.6.   40 GB HD, originally had 10GB HD. Laptop has a 15" screen (12" x 9"), if using Samsung SyncMaster 205BW (20" TFT-LCD Monitor) at 1024x768 it is a bit distorted.

Picture of about:config settings for using a custom template.

The url name are created when the corresponding profile is brought up and are named through the profile about:config variable "extensions.infolister.file", all use the same template which is named in the add-on options for infolister.

Mouseover Link for ID, or use the bookmarklets Paren_Tips to display all descriptions, and/or href: to display urls within listing.  Wish that InfoLister provided a compatibility text indicator like exclamation point shown in Tools, Addons, Extensions.

The descriptions provided above come from the “Infolister” extension as provided by each extension's own author, for more complete descriptions and notes on my usage of these extensions see my Extensions Table on my Firefox Customizations page.   Firefox generated about:plugins list may not be up to date compare to infolister listing below.

Important notice:  www.extensionsmirror.nl site has been changed to forum.addonsmirror.nl and many old extensions have not been updated internally, but you will find most of them at new site and also on addons.mozilla.org or as projects at mozdev.org  [2007-04-13][2008-05-12]
Example:  http://www.extensionsmirror.nl/index.php?showtopic=2796 must be changed to http://forum.addonsmirror.net/index.php?showtopic=2796

You can compare older and newer versions of the table by pasting into a before and after text areas online with Quick Diff Online Tool, an Online Tool to do a 'quick and dirty' diff of two text or code fragments.  Or using the extension PageDiff :: Add-ons for Firefox, to see HTML-code(text) differences between web pages

AVG Safe Search, see directions to uninstall by removing the LinkScanner component, which does not work in Fx2 or in Fx3 so was added to AVG anti-virus very prematurely (April/May 2008).

Disabled in above listing (#disabledlist)

Unfortunately InfoLister will not create a disabled only list, so the another table was created at the very end of this page, see no details.

These are 19 extensions I've disabled in 2.0.0.12 on * 2008-02-08

Disabled Extensions (#disabledext)

The following 15 extensions are disabled on 2007-11-22:  "About This Site Bookmarks", "Anchorun", "Autocomplete Manager", "iMacros for Firefox", "KGen", "Line Marker", "MeasureIt", "Mouse Gestures", "MultiSidebar", "OPML Support", "Perma Tabs", "RealPlayer Browser Record Plugin", "Server Spy", "TestGen4Web - Script It All".

Somehow all extensions became enabled and was getting an error

and Verizon, Yahoo, Overture were spitting out crap (try these) for 404 (not found) errors.  Possibily lost a dns server that I placed before Verizon.  To fix this now have to change the modem's settings.

The following extensions were disabled 2011-06-26 so that Firefox 5 could run quicker. Their functions were not added to Firefox 5, just another case of losing more extensions and functionality due to updates. about:accessibilty, about:me, Dom Inspector, FxIF, GoogleEnhancer, InspecterWidget, LinkChecker, Location Navigator.

Some similar listings

Script Busy   (#scriptbusy)

On titlebar (Not Responding), also seen as Unresponsive Script, or screen whiteout.

Something to test after adding/enabling an Extension: Ctrl+A (select all) followed by right-click to bring up context menu.  Big problem if instead of context menu you get "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete [Stop Script] [Continue]". These extensions are a problem: on my machine (600MHz) and have been disabled or uninstalled:

This listing was created by the Infolister Extension, and shows the Extensions, and Plug-ins that I have chosen.  You can learn more about my choice of extensions at my Firefox Customizations (notes) webpage.

The customized template used to create this page can be found at http://www.mvps.org/dmcritchie/firefox/infolister_template.txt  and you can create your own template if you want something different than the default listing see InfoLister Help: Templates syntax [http://mozilla.doslash.org/infolister/templates/]

Enhancements to Infolister that would be appreciated

maxVersion had been included for the next InfoLister extension update (after 0.9f) to be able to show the maximum Firefox version that the Extension will run on, which should help in planning with upgrading to a major Firefox version.  Never got the update text to be include later [%minVersion% - %maxVersion%].  Did find a comment though possibly with needed code.

user update date (timestamp) so can see latest changes made (the "Extension Manager Extended" displays this information) which is actually for date installed or updated by user which would be critical to finding a problem extension. If available would put in same cell as author and before the author so table can be sorted -- needs to be yyyy-mm-dd hh:mm so can be sorted.

HTML tables can be sorted with the "Sort Table" bookmarklet.

Be able to find and list the extensions icon, even though would only be seen locally and not on a listing shared on the web.
Don't really see how these are packaged, the addons list seems to be able to find them okay.  Meanwhile found some by searching on "/skin/" or "16.png" or "24.png" or "32.png".

To see a chrome link, it must be copied to the location bar, as they can't be used directly as links.  If the chrome link is entered as a link, you can use the linky extension to help with manually opening the link.  The images can be seen as images locally.
Example:  chrome://copyurlplus/skin/copyurlplus16.png {*copyurlplus16*PICTURE*} and iconURL – chrome://copyurlplus/skin/copyurlplus32.png {*32*PICTURE}
                chrome://copyurlplus/content/about.xul
Example:  chrome://infolister/skin/toolbar16x16.png {*16x16*PICTURE*}chrome://infolister/skin/toolbar24x24.png {*24x24*PICTURE*}

{*forced*PICTURE}Compatibility Testing Disabled: (#compatibilitydisabled)
Caution:  using incompatible extensions may increase your incidences of crashes or other malfunctions.  If you are testing Firefox Beta software then you are already assuming additional risk, and would not be able to test extensions without turning off extension compatibility testing.  As far as a warranty is concerned there is none anyway no matter how you use Firefox, or Beta, or extensions, or configuration changes from any location.  [Legal, EULA, TOS]

extensions.checkCompatibility set to False in about:config

More information:  Forcing Extensions by creating extensions.checkCompatibility and setting to False.  You are using Disable so don't toggle Enable which refers to overriding ALL deprecated extensions not specific to anything selected.  Those that have been forced are marked with an exclamation point ( ! ) on their icon, but there is no indication on the InfoLister listing (this listing).

extensions.checkCompatibility.3.6b     False
is required for 3.6b (betas) and the practice will continue unless unstopped into later versions as well.  References ref and Updating extensions - MozillaZine Knowledge Base, You can configure Firefox and TB to update your extensions and themes automatically, and you can even disable/prevent auto-update for individual extensions.
 
Unable to install themes or extensions - Firefox - MozillaZine Knowledge Base

user_pref("browser.tabs.closeButtons", 3);
user_pref("extensions.checkCompatibility", false);
user_pref("extensions.checkUpdateSecurity", false);
user_pref("general.warnOnAboutConfig", false);

Firefox 3 Secure Extension Updating: Extensions can be installed from AMO and from secured sites without a problem.  In order to test from another source set extensions.checkUpdateSecurity to False (see bug: 378216).  for more information see Unable_to_install_themes_or_extensions_-_Firefox and additional references of interest (that might get removed from the article):  Extension Versioning, Update and Compatibility - MDCUpdating extensions for Firefox 3 - MDCFirefox 3 for developers - MDC

A recent problem with addons.mozilla.org is that you can't install an extension {ignore*PICTURE*} that you don't already have if the maxVersion is insufficient, and you will see a grayed out install button.  You must login to addons.mozilla.org using the login link in upper right corner, after you have logged in you will see the words "ignore version check" added to the grayed out button, click on those words and then the button will be green, and the next step is to click on the "Install Now". 

If you then get a message like "Launchy 4.2.0 could not be installed because it is not compatible with Firefox 3.0.", it is because you have not set extensions.checkCompatibility (as Boolean) to False as a new Boolean variable in about:config.  Next comes up the idiotic "This might void your warranty!", written by idiots for idiots -- you know what to reply to that, but first don't forget to uncheck the box.

Another way and this does not require a log-in is to access the "See All Versions" (Complete Version History) link on the add-on details page (e.g. see https://addons.mozilla.org/en-US/firefox/addon/1865) that takes you to the Version History page which will let you download all known versions of an add-on independent of the version of your browser. [Basil Hashem 2008-04-01]

In an Absolutely Unacceptable and IRRESPONSIBLE behavior Firefox developers decided you must install so-called incompatible extensions with "Nightly Tester" tools and that it will destroy the red exclamation points that indicated version incompatibility. This is the one indication that you had as a tattle tale (warning) that you have overridden compatibility and may cause problems later, and that you might be advised to look for a more current version that may not directly update.  So if I already had it I can have the red warning exclamation point, but if I install a new profile, or help someone else, I can't.  This is absolutely insane.

Bookmarklets   (#bookmarklets)

You can make the links on this page visible by installing the "HREF Visible" bookmarklet, which I tried to include here but it would not make it through the template code in usable condition.  Go to the link and drag the named bookmarklet to your bookmarks bar to install it -- you can also give the installed bookmarklet a keyword of "href:" to provide another means of accessing it.  Would also recommend installing and using the "Paren Tips" bookmarklet.

This list could be improved with a SCRIPT function within the template or with a change to InfoLister so that the TITLE would return doubled quotes ("e;"e;) within so that title="%description%" would properly process embedded quotes.  Using title='%description%' won't work either because some descriptions contain single quotes (Menu's).  Could also be needed to process ampersands within homepageURL
