Free Software Directory:IceCat extensions (proposed)

See this page for approved add-ons listed in this page. See GNU IceCat add-on third-party repositories for tools for the add-ons in this page.

Currently over 500 stable and essential add-ons are listed.

Disclaimer: This page are compiled from two add-ons repositories, Trisquel web browser (~500 add-ons, merged 2015-03-18), and free add-ons from A List of Stable, Non-Conficting and Essential addons (picked from ~700 add-ons); Many add-ons are present in both repositories so its hard to say exactly how many add-ons that have been reviewed. Also note that the repository on this page has superseeded the these repositories for the following reasons: Many add-ons have been added that is not found in these repositories as add-ons here have been updated, removed, replaced for following reasons: incompatibility with IceCat 31.5.0 (based on Firefox ESR 31.5.0), buggy, superseeded, bad rating, not significant popular, Service as a Software Substitute (SaaSS), and known mass surveillance services (commercial cloud/social media). The reason why you don't find these add-ons on the IceCat page is because most of them have not been approved by the FSF. This list should be merged back to the Trisquel web browser repository meanwhile to do any good.

Add-ons that were listed on addons.mozilla.org without any license were manually downloaded and reviewed.

Urgent: Please help us setting up Greasemonkey as HTML5 Video Everywhere!, and GNU Gnash, are not sufficient to play videos on some popular websites. Some free Greasemonkey User Scripts, like ViewTubePlus can can be used to play these videos.

Add to Search Bar	[ visit page] (compatible version: https://addons.mozilla.org/firefox/downloads/file/285224/add_to_search_bar-2.7-fx.xpi Make any pages' search functionality available in the Search Bar (or "search box")... Review notes: “You can add many search engines to your firefox search bar from the Mycroft Project website. I use search engines for many purposes from searching Song lyrics, to use the dictionary and the thesaurus, to search for an email in my GMail inbox, to search for people on Facebook etc. This addon is indispensable to me. I use it in the following ways (A). From the mycroft project website, I have added Google search for pages within the last 1 day, 1 week, 1 month and 1 year to the search box. This is immensely helpful. If I want latest news, I only search for webpages that have been updated/created within the last 1 day/1 week and so on. If I want to know about the latest research on Down's syndrome, I search using the Google search for 1 year. Perfect! (B). My translation needs are very basic. I use these three more efficient methods to translate pages or text within pages: 1. Bookmarklets 2. Flagfox addon 3. Simply go to the google translate page and use the "Add to Search bar" addon to right click in the translate box and Add it to your firefox search engines! Voila, now you can simply paste text in your firefox search bar and get its translation in a new tab. It becomes even better if you use the addon "Selected Search" too. With Selected Search, you don't need to paste your text in the search bar and press enter. If you have 'Selected Search' you only need to select the text you want to have translated and then press the button for google translate among the search engines that pop-up - a new tab with the translation pops up.” - https://addons.mozilla.org/en-US/firefox/collections/ChessWriter/my/ Category:

Bookmark All	[ visit page] Review notes: “Very useful to save tabs in a hurry, requires only one click. See also "Bookmark current tab set". “ - https://addons.mozilla.org/en-US/firefox/collections/ChessWriter/my/?page=20 Category:
Bookmark Current Tab Set	[ visit page] Review notes: “ Bookmark Current Tab Set in one step( all tabs are bookmarked to a location you have already set in the settings) or two steps(a dialog pops up allowing you to chose a name and a location for the folder where the tabs will be bookmarked to). See also the addon "Bookmark all" which allows one step bookmarking described above. The advantage of "Bookmark all" is that it gives you a button that you can place anywhere you like and press to bookmark all addons - more convenient, but you cannot chose a custom name and location for the new folder thus created. “ - https://addons.mozilla.org/en-US/firefox/collections/ChessWriter/my/?page=23 Category:

Review notes: “If you want to check a page for changes occurring over a period of days/weeks/months, use "Update Scanner". If you want to be alerted about changes that occur over seconds/minutes/hours, use "Check4Change". Following RSS Feeds, if a page makes them available is the best way to keep abreast of changes made to a webpage, but if a webpage does not make RSS feeds available, then using "Update Scanner" or "Check4Change" is the only way to check whether any changes have been made to the webpage.” - https://addons.mozilla.org/en-US/firefox/collections/ChessWriter/my/ Category:

Color Transform	[ visit page] Review notes: “In this list you will find the following addons to alter the look of a webpage 1. Color Transform 2. Blank Your Monitor 3. Textise 4. Column Reader 5. Tranquility 6. Readable. 7. No Squint Out of these BLANK YOUR MONITOR is my favourite because it is extremely fast at transforming the appearance of a page. It changes the page as per your settings within an eyeblink of your pressing the button. COLOR TRANFORM is almost equally fast, it has the advantage of being a lot more customisable; But Color Transform requires you to click on its button twice(rather than once like Blank your monitor) i.e once to open the pop-up that lists the various kinds of layouts you can choose, the second time to select a layout. TEXTISE simply gives you a text-only version of a webpage which is useful if you want to save a webpage, but you can also use it to improve the readability of the page. COLUMN READER: If you read extremely long wikipedia articles, you will like Column Reader. For simple one or two pages long articles you should use either TRANQUILITY or READABLE..... Column Reader, Tranquility and Readable all take a longer time than the other addons to remove the clutter from a webpage. Column Reader takes the longest time, but improves readability the most from among Column Reader, Readable and Tranquility - this is why its time consuming transformation is worth it only on longer pages and research articles. 7. NO SQUINT: Allows you to zoom in/out of a page. What is special about it is that you can zoom the page separately and zoom the font size of the text separately and Save the settings!. So you can enlarge the text more than you enlarge the images if you so desire. The ability to save website specific settings is unique to No Squint from among the 7 addons I have described. [My preference: Use Blank your Monitor for small pages and Column Reader for longer pages like Research papers etc.. Blank your monitor is sufficient for most purposes once you have customised a webpage using No Squint and saved the settings] “ - https://addons.mozilla.org/en-US/firefox/collections/ChessWriter/my/?page=17 Category:

If you use Copy plain text 2 with Autocopy 2 then you can autocopy everything as plain text if you wish. “ - https://addons.mozilla.org/en-US/firefox/collections/ChessWriter/my/ Category:
