Summary: Interactive tutorial to show some of the things that can be done with bookmarklets in a browser, some features of the Chrome browser, and a collection of the extensions I am using in Chrome.

Author: David McRitchie

You can test out the bookmarklets on this page, a bookmarklet adds "one-click" functionality to your browser.  This page essentially contains most bookmarklet examples from my "(newtab)" page and work I thought would save time composing Evernote note page but Evernote did not include the links with JavaScript code.  You may begin by clicking on “parentips:”, which will list all of the tooltips you mouseover to see as notes within parentheses to right of the associated element.  Bookmarklets are tools -- do not concern yourself with their code, relax and see what they can do.  You can always find additional bookmarklets with Google Searches.  You can drag a single bookmarklet to your bookmarks toolbar or any bookmark folder.  (Link for importing bookmarks (bml.html) for bookmarklets you see here.) This page has approximately 181/509 (updated) and the file has 190/217 bookmarklets within bookmarks.  To install 1) copy file to your drive, 2) import into your browser, 3) move C.BML or BML folder to your toolbar, 4) delete the imported folder you created with these steps.  I added several bookmarklets but one of general interest would be domains, where you have a page with lot of links and want to see where they are but not interested in the complete urls.

(After testing 1 or more bookmarklets, use F5(Reload) to refresh page back to normal),
Test first with: domains:, href:, brj:, parentips:, int:, borders:, charcnt:, id: (or ShowClassesAndIDs), comments:, src:, wrap:, hidivs:, and then bml:

Sorting: (#sortntables) SortSelect: (example at right), SortTable: (see Table)
[to Sort Text Lines, see beside #tools, bookmarklets don't sort links, MSWord does]
Source code (HTML):  Used to use Ctrl+U to see source in Notepad with modified Firefox, which was my preference for viewing and modifying my own code.  Prefix url in address bar with "viewsource:" to view source in all browsers, no bookmarklets required; while a formatted list may be better to view someone else's code the text does not wrap in your browser.
Saving changed appearance:  Bookmarklets only affect the page while viewing, but if you would like create a new copy to include your bookmarklet invoked changes, you can use a bookmarklet to get the source with your bookmarklet and all styling changes included using: generatedsource: partialsource:.
Spelling and Grammar  sp: - spelling  undosp:  Don't know why no one else thought of undoing edit mode other than by by a Reset(F5), but you have to do it from a bookmark not from the page.  More information see Identifying Spelling and Grammar errors below [5 minute video available]

It appears that a bookmark with substitution using %S (Smart bookmark) will work on one computer with Chrome, but not on another one with Chrome and not in other Chromium browsers.  the bookmark title begins with the shortcut and has %S or substitution. testing: of w:   (can't duplicate here guess it actually has to be a bookmark).

sharing and saving bookmarklets : 

• Bookmarklets can't directly add to the clipboard.  If you want to create HTML links from tabs use an extension such as "TabCopy" (Chrome from extension button).  A much better extension is available in Firefox -- "Copy Selected Tabs to Clipboard" invoked from the Firefox tab context menu [Evernote note]), will pick up %DESCRIPTION% at most sites but not at addons. 
• Bookmark Descriptions are not available through any Chrome extension as Chrome does not have bookmark descriptions.  For Safari you can try: Tabs to Links on the Mac App Store or "TabLinks" Safari Extension - BrettTerpstra.com (future).  Firefox no longer has descriptions nor keywords on Firefox Bookmarks so I stopped using Firefox (don't confuse keywords with the useless tags).
• Saving webpages with bookmarklets or saving exported bookmarks to Evernote for preservation will not work very well for you as all bookmarks containing JavaScript have all of the JavaScript code removed.  Same thing occurs if you try to paste a bookmarklet link with javascript into email.

Two more dictionaries: EasyDefine,  HyperDic hyper-dictionary,  (presented as links not bookmarks)

Repetitive: 99:, 

Created for this page (WIP):  domains:,  fav:,  favicons:(below/not-working), href#:,  src:, 

Also needed favicons in links exposed changing icon="data:... to <img src="data...

src="lesson_from_newtab_files/Image [75].png" type="image/png" data-filename="Image.png" alt="test image for bookmarklets test" /> src:test /* src=src.substr(indexOf,'['); */

favicons: (not working)

Checkmarks:

    chktoggle: (chk)   tickall: (tic) (:: Check boxes belong within form tags ::)

The checkmark bookmarklets would have been great for Gmail as the mobile version does not have a global check/uncheck box for the mail search hits, unfortunately Gmail uses JavaScript not normal checkboxes, so the two bookmarklets do not work for f.

According to "search links" the following bookmarklets on this page have selection:  def: define, highlight:word, mag: (magnify), partial source, words: (cnt), wordcnt: (selection),

Bookmarklets are tools: You do not need to know anything about how bookmarklets work to use them, just like you don't need to know anything about the code in browser extensions to use them.  Bookmarklets incorporate JavaScript code and can be very powerful though incorporating very little code.  You can use several bookmarklets on a page to provide enhanced reading.  You can paste the first line below into your address bar simulating use of a bookmark to run the code.  You cannot do that and a heck of a lot of other things in Firefox anymore though.

Mass Install (#massinstall) All of the bookmarklets above are available to be installed by replacement in Android.

1. Read in Bookmarklets for Tablet (  http://dmcritchie.mvps.org/android/ bookmarklets_for_tablet.html   w/o space ) using "VT View Source - Android Apps on Google Play" on tablet, which allows you to view source of files on tablet and on web, then save on your tablet in /mnt/sdcard/BookmarkSB/bookmarks_for_tablet.html,
2. then in "Bookmark Sort & Backup (BookmarkSB) - Android Apps on Google Play" you can restore (replaces all bookmarks in Browser) from the local file, you can sort the bookmarks if you want them sorted in the default Browser. You may need to sort them in descending order before importing them into another browser such as Dolphin.
3. Bookmarks installed in Browser can be used or imported into other browsers, some have a folder that simply contains "system bookmarks".

History [Ctrl+H] (#hist)  (in Firefox the equivalent shortcut would be Ctrl+Shift+H and be able to show more information in a sortable table)  The blue Stars in the listing indicates it is also bookmarked.

Bookmark extensions: (#bmext)

"Recent Bookmarks" Chrome extension is useful it shows recent bookmarks that you considered important enough to save; whereas, your History (Ctrl+H) shows what you looked at.  Has scrollbars.  (see dropdown in first image).   No extension was really needed in the old Firefox (FF 56.0.2 was still good) because columns could be sorted in the Bookmarks Manager without being permanent (10 ways of sorting including unsorted); nevertheless, makes access to recent bookmarks a lot easier.  Another nice feature is that you can copy and paste from the display with included favicons.  • Can't edit a bookmark, but can delete.  (a similar extension for current Firefox users is available.)

  Since Chrome does not have scrollbars in menus or bookmarks (Except in Bookmark Manager), I recommend: both of these have scrollbars and search.  Firefox has better functionality, even though neither browser has scrollbars on bookmark menus, Firefox has an adequate Bookmarks sidebar (Ctrl+B) from which you can use search and can use bookmarklets

"Bookmark Manager and Viewer" drop-down for bookmarks includes scrollbars (can't implement bookmarklets on active page, so only good to help find bookmarks, you will have to try your luck with the address bar to use bookmarklets). The star changes to a filled Blue star if the active page is bookmarked.  • Can search, edit, delete, and open bookmarks.  No good for invoking bookmarklets.
[Has a couple of tricks up its sleeve 1) one is after a search you can validate website URLs (slowly). Unfortunately bookmarklets are not websites so they are all marked as invalid and all of the Chrome extensions (chrome google.com/webstore) are marked as invalid; nevertheless, it could be useful. 2) The other trick is to correct the titles if they've changed overtime Unfortunately I purposely change a few titles so that they will sort where I want to find them or to improve their titles, so that would be a bad thing for me to use and especially since bookmarks in Chrome do not have descriptions (and Firefox attempted suicide by imitating Chrome).]

    "Bookmark Sidebar" (best) It is the only one of these that can run bookmarklets on the active page. There is a disappearing scrollbar that is very difficult to use, but you can not do much without it. Mouseover shows URL and if search was used will also show the bookmark folder. Sorting available: User-defined, Alphabetical, Most used, Recently used, Recently added; the sort applies to all bookmarks when viewed in this extension and is independent of ordering you have in the Bookmarks Manager(Ctrl+Shift+O). However, warning, if you do sort a folder via Bookmarks Manager then you permanently change your user-defined ordering for that folder. Scrollwheel does work and will show location of the scrollbar thumb. Thumb size and location gives you an idea of how far you are from the top and bottom and how big the area is compared to the part you are viewing. Arrow keys don't work for this "wonky sidebar" which covers over some of the page and fogs over the page. Sticky menu: return to the same spot later with the same folders open. • Can search, edit, view date added with Ⓘ, delete and open bookmarks, can utilize bookmarklets.  (Firefox users have a much better Bookmarks sidebar builtin, though it doesn’t include temporary sorting)

Ad Blocking extensions: (#abp) See my answer in "Is there a Chrome extension that blocks the messages that tell you to turn off the ad-blocker? - Quora, where I tell you what extensions to install and how to customize them.  Adblocking extensions basically all use the same filters such as used in both Adblock Plus and uBlock.  To see what filter blocked each blocked item on a page use Inspector (Ctrl+Shift+I), then choose "Adblock Plus" to right of Elements, then reload page.

• Adblock Plus - free ad blocker     must install filters, same with other adblockers (number tells how many links blocked).  Besides choosing filters make use the "🚫 Block Element" to easily add your own filtering, be prepared to undo mistakes and conflicts.
• BehindTheOverlay sometimes an overlay tries to get you to subscribe but you just want to view content for now as in collections of instagram.com images found in google
• Bypass Paywall (see below) [not in Webstore]
• Cookie Deleter    delete cookies on a site, use on paywall sites that limit number of free articles per month.
  Example for installing and invoking extension foils].  
• Hide That, hide or remove selected elements on a page. Useful for removing invasive adverts, banners and overlays. (context menu i.e. right-click)
• History Blocker by Site     domains you don't want to appear in your History (Ctrl+H)
• Paywall  [$$] supposed to be showing $$$ for paywall site links (symbol is blank on extensions  toolbar area)
• PopUpOFF - Popup and overlay blocker - Chrome Web Store Select level at each site Tried using AdBlock+ to remove but it prevented scrolling --this extension worked on a site next is NYT. (Also available in Firefox).
• uBlock - free ad blocker similar ABP if you have to disable to read a site you probably have to do same for both
• uBlacklist tell Google Search to block future references to domain by clicking on "Block this site", if you accidentally click on on the words, you can still cancel out of the blocking request.
• Unpaywall  click on padlock at right edge of screen to view for free
• Video AdBlocker for YouTube™ Extension   completely different from ABP, will delete third party ads inserted into the video.

Chrome on Android does not allow extensions, so suggest using the Kiwi Browser which allows you to run Chrome extensions. Converting an Amazon tablet to Android provides a better browser tab page using KiWi.

Make these symbols show up in listing with the #hiregex bookmarklet.
Context menus are named because their content changes depending on where they are used.  Each context item has its own context menu.  Those with no Favicon belong to the browser, and those with a Favicon belong to an extension.  Examples of context menus (Tosh, ASUS)
Context menus (along with tool tips, and left-click menus) also exist for {A} address bar and toolbar icons.

These are the Chrome extensions on my Toshiba, listed in Alphabetical Order  most come from the Chrome Webstore , may also be on Android using the Kiwi Browser an APP from the Google Playstore .  Kiwi is the same as Chrome but can use Chrome desktop extensions which Chrome on Android cannot.
 
Search for Chrome and Chromium Extensions at the Chrome Webstore

1. Adblock Plus - free ad blocker , Block YouTube™ ads, pop-ups & fight malware! (see Ad Blocking extensions above)
2. Adblocker for Youtube™, automatically blocks all ads on YouTube ™, including pre-roll video ads, text & banner ads.
3. Amazon Assistant for Chrome (official extension)
4. BehindTheOverlay , One click to close any overlay on any website. (or Ctrl+Shift+x or Cmd+Shift+x)
5. Bookmark Manager and Viewer, from Star on extensions bar.
6. Bookmark Sidebar  Bad approximation of a sidebar, but it is a toggleable sidebar with all your bookmarks (can run bookmarklets from here, because associated with the active tab).
7. Bypass Paywalls Clean for Chrome GitHub , obtain from GitHub it is not in Chrome Webstore, special instructions, easiest to install for Android using .crx file; otherwise, Chrome Desktop instructions.

Kiwi extensions, Kiwi Browser (an app from the Google Playstore) is the only Chromium browser that allows you to install desktop extensions from the Chrome Webstore.  I have installed the following extensions on my Amazon Tablet which has been converted to run apps from the Google Play Store.
The extensions I have installed are as follows: Cookie Deleter,  HTML5 Outliner,  List Opened Tabs,  Tab Count,  TabCopy,  and  Textarea Cache. 
Warning, don't install any extension on Android that puts new tabs at the end of the tab bar (renders Kiwi unusable and you have to uninstall and start all over again. (i.e. "New Tabs at End 3000" (do not install).
The bookmarklets I installed into my bookmarks so far are as follows:  id:,  li: (bullets#),  trows: (table rows),  zapcolors: (restore HTML default colors).
On Android Chrome I have all of the bookmarklets shown at top plus a lot more bookmarks and bookmarklets.  But as already mentioned no extensions are available.

Firefox extensions, these are the extensions on my small ASUS laptop. Started list with Fx79. My Toshiba will continue to use Firefox 56.0.2.  See my article posted in Quora "What are some unique features of Mozilla Firefox that other browsers don't have?".  Many Firefox extensions make use of context menus and are better written so you won't have the clutter of extension icons that you see in Chrome, nor the need for as many extensions.  (You can compare my modified comments to the author's short description by invoking the [parentips:] bookmarklet at the top and then returning here.)
Firefox has context menus to deal with Frames, Background Image, Cookies, DOM & Style Inpector.

I had the new Firefox on a small laptop that was destroyed by a Microsoft update.  I did verify that the extensions listed below are still around.  Firefox would have less trouble with extensions than Chrome, but I'm using Older Firefox (56.0) to update my webpages when not using Chrome.
 
Search for Firefox™ Extensions -- For Current Firefox™, purposely broken for versions after 56.0.1 to match Google "Chrome" without bookmark descriptions and bookmark shortcuts, and can't change the Chrome of Firefox™ all of which predates Firefox™ which in turn predates "Google Chrome™".  That is why I no longer use Firefox™.  As stated earlier Vivaldi™ tried unsuccesfully to retain keyword and description, but you can't sync to other browsers, nor import nor export those items. As already mentioned if you want to use extensions in Chrome™ on Android™ you must use the Kiwi&tm; browser instead.
 
Firefox Extensions:

101. Adblock Plus ,  Block pop-ups and annoying ads on websites like Facebook and YouTube. (click on Firefox to install).  For more information on Adblocking extensions see Adblocking (#ABP) above, those extensions are in most browsers.

109. Copy Selected Tabs to Clipboard 🦊, format selected tabs into text or links may include Title (as link text), URL, Description (as link internal title, and other Meta data.  For this portion I used a pattern like: Actually had to use an older version of Firefox and Multi Tab Handler, as Firefox has made addons tabs protected in some manner.
     <li><a target="_blank" href="%URL_HTML%" title="%DESCRIPTION_HTML%">%TITLE_HTML%</a>,&nbsp; </li>%EOL%%RT% — and copied to the rest of the line the important parts from the Description along with my own comment.  {T}

Button will be hidden on the Extension Overflow menu.
125. Textarea Cache 🦊, save text from text input areas automatically.  If you get kicked off you should be able to recover what you typed.  If you just filled out a web forum and wished you made a copy just after you sent it off, then this extension will help a lot. 00000 don’t lose an answer you spent time working on.

Saving space in Firefox toolbars (#fxspace)

• Remove icons at left of "..." on address/location bar via that 3dots menu.  Remove the head immediately to right of address bar by hiding it in the extensions overflow.
• Change black scrollbar to lighter wider scrollbar by changing theme in Customize in the hamburger menu from Normal to Compact. (not a space waster but it is an annoyance)
• Change density from Normal to Compact which is also in Customize.
• Hide these extensions in Extensions Overflow:  OverlayRemoveAuto / Tab List / Bookmark Menu / Context Menu Unblocker /
• Hide these in the customize pool, because you do not need to use the extensions button to use them: 
    / Chrome Store Foxified / Copyfish / Keywords / Link Properties / Search by Image / User Agent / web Archives /

Firefox on Android:  There are only a few Add-ons for Firefox that are deemed to work on Android and you will be redirected to addons >> Android which may take you to the Chrome Webstore.  Installed:  "Search by Image",  Web Archives".

Mozzila destruction, and why I don't use the new Firefox on my laptop 

• Removed keyword shortcuts, can no longer be imported/exported or used.  Vivaldi (browser) retained nickname which could be used for keyword shortcuts, but no way am I going to fill in 1000 or more keyword shortcuts by hand each time.  This page has only a fraction of what I have.  Vivaldi does not import or export them with bookmarks because they were never in Chrome so place in records and database do not exist.  Vivaldi does have a better layout for browsing in that you can compress toolbars, but lacks meaningful coloration of toolbars.
• Removed description from bookmarks which could be copied from webpage description.  Absolutely destroys meaningful bookmark documentation vitally needed for research and bookmarklets.  Vivaldi retained them but like nicknames, you can't import or export them so they are useless.
• Removed ability to change Chrome (color and appearance of toolbars, etc), so no longer have scroll bars on menu and bookmark menus.  Gone are the days when you could make such modifications and without wasteful extensions the very same day you first installed Firefox.  It is no longer "Have the browser the way you want it".
• Like all of the other browsers decent scrollbars that let you know where the scrollbar thumb is are hidden, or so small you can hardly see them.
• Can't change Chrome also means can't get rid of bookmark and folder icon from the bookmarks toolbar and color text for bookmarks in red and folders in dark blue.  A 1-3 character name is more descriptive than a favicon when space is tight

Extension links for Chrome and for Firefox (use search on page).  Extensions for Chrome may be available in other browsers by the same author under the same or similar title, or you should at least be able to find something comparable in other browsers.

JavaScript bookmarklet summary: (#summary) for all bookmarklets on this page in alphabetical order, plus more bookmarklets, all with link text titles suitable for bookmarks and importing see bml.html link at the top of this page (directions included).  List was created with [searchlinks:] bookmarklet searching for "JavaScript".  [searchlinks w/o ##] can be for sorted in MS Word for comparisons.
