Using Firefox/Extensions
Extensions are small add-ons that add new functionality to Firefox, but should not be confused with plug-ins.
In Firefox, add-ons is a general term that in Firefox is applied to extensions proper, themes, userscripts, userstyles, service workers, plug-ins, spellcheckers and language packs. Extensions rely on built-in frameworks and APIs within Firefox, and are integrated into the browser after installation. Whereas plug-ins, such as Adobe Flash, use programming not native to Firefox, and are usually embedded into a web page only when said page contains code that requires Flash to be loaded.
Extensions that use the legacy XPCOM, XUL, and JetPack frameworks, are supported until Firefox 56.0. These are known both as legacy extensions, and legacy versions of Firefox, respectively. In late 2018, Mozilla ceased support for XUL-based extensions, and no longer hosts them, though various ways of obtaining legacy extensions still exist.
WebExtensions were initially supported in Firefox 48.0, and beginning with Firefox 57.0, only WebExtensions are supported.
What can extensions do edit
Extensions can add anything from a toolbar button to a completely new feature. They allow the browser to be customized to fit the personal needs of each user, if they need additional features, while Firefox proper remains relatively unadorned.
Many links herein will not necessarily point to a specific extension, but rather to general links at the Mozilla Addons.
Downloading and installing edit
Mozilla Addons edit
Most extensions for Firefox, SeaMonkey, Thunderbird, and derivatives are available at the Mozilla Addons site, which hosts well over a thousand extensions. The great number of addons may make it difficult for people to find what they want.
Mozilla Addons has easy-to-use pages linking to extensions by category, popularity, or recommended status.
There are many themes available, which make Firefox more attractive. The most popular themes are listed here.
Mozilla once launched Fashion Your Firefox, an easy-to-use service for users who didn't want to go through the entire library of addons to choose just a few good ones based on what they use Firefox for.[1] Fashion Your Firefox has since long been discontinued.
The below sections herein provide links to specific extension categories at Mozilla Addons — this means that the information will stay up-to-date.
Alternative sources edit
Since Mozilla no longer hosts legacy extensions, then their installers in the form of XPI files are still available from a number of places:
- back-ups by various open-source volunteers;
- occasional mirrors of Mozilla Addons FTP site;
- the developers' own websites, or original web resources (MozDev, GitHub); and
- at the Internet Archive WayBack Machine.
The Internet Archive serves as the resource closest-possible to the original Mozilla Addons site, and hosts most extensions' description and version pages. If an extension page was archived before October/November 2018 (inclusive), then it's mostly functional, too, such as showing if an extension is compatible with the visiting browser.
The requirement to see an extension's archived pages is to know its original address at the Mozilla Addons site. This can be found out from an extant extension's install information in a browser, or by searching the Internet using the addon's name.
If the "Add to Firefox" button on the archived page of an extension, or in its versions page is active (usually coloured green), then clicking the button may redirect the user to the extension's installer (XPI) file, but not always. The workaround is to right-click on the "Add to Firefox" button, and open the button's link (that directs to an XPI file) in a new tab. This would lead to a couple of redirects to the correct XPI file. Note also, that you'll have to allow installation of extensions from web.archive.org in an extension install notification window.
Not all extension installers are available from the WayBack Machine, due to not having been archived when they were originally available.
Alternative, and in some cases, more technical download sources of extensions for Firefox are available at XULRunner Hall of Fame at MozDev, at mirror.umd.edu, and at http://ftp.metu.edu.tr.

Content blocking edit
- Adblock Plus — Blocks or hides advertisements and other annoyances from web pages, while still retaining the correct page format. It is designed around blocklists, and allows you to block flash and image banners built into the web page, as well as scripts. You add your own filters using wildcards (*) for simple custom filters, or regular expressions for advanced ones. Adblock Plus automatically downloads a pre-set blocklist, and provides additional lists of blocklists to enable and download, based on region or function (such as cryptominers).
- Flashblock — A legacy Firefox add-on to easily block Flash, Silverlight, and HTML5 animations. The initial Flash file in each embed does get downloaded, but its animations are replaced with a click-to-play icon. Additional downloads via Flash are won't be initialised either.

| This extension was no longer maintained as of October 2011,[8] and support for Firefox 4.x and greater[9] would not be forthcoming, due in part to 'constant' changes in GMail.[8] GMail Notifier was then marked as discontinued since at least October 2012.[10] • The claim of compatibility[11] with Firefox 56.* in the extension's versions page is therefore dubious; neither does the addon's main page deem versions newer than 3.7a1pre compatible.[6] • The peak number of users, as recorded by the Internet Archive on 17 October 2011, was 189,938.[8] | |||||||
