Tag Archives | Firefox add-ons

Firefox add-ons, sometimes also called extensions or addons, are small programs written in JavaScript that add, remove or modify functionality of the Firefox Internet web browser. The majority of browser extensions for Firefox are community-based, with only a handful of official additions by Mozilla employees.

Add-ons serve a variety of purposes, from adding functionality to the Firefox browser, like NoScript which improves security of Firefox by disabling all script in the program by default, over add-ons that improve your workflow, like Multi Links which enables you to open multiple links at once, to extensions that change the look and feel of the browser.

The official Mozilla Add-ons repository hosts thousands of add-ons sorted into categories like Bookmarks, Tabs or Web Development. We are regularly reviewing the best, new and updated, Firefox add-ons so that you do not have to browse the Mozilla website manually every other day to avoid missing out on a great new extension released recently to it.

Add-ons usually remain compatibility with new versions of Firefox. This has not always been the case in the past, especially when Mozilla upgraded a core feature of the Firefox web browser. We cover news about these changes in the main Firefox category as well to keep you informed when changes happen that may affect compatibility.
