Add-ons are small pieces of software created by people all over the world, that add new features or functionality to your installation of Firefox. Add-ons can augment Firefox with new search engines, foreign-language dictionaries, or change the visual appearance of Firefox. Through add-ons, you can customize Firefox to meet your needs and tastes.

  • Extensions
    Extensions add new features to Firefox, or modify existing ones. There are extensions that allow you to block advertisements, download videos from websites, integrate more closely with websites like Facebook or Twitter, and add features you see in other browsers.
  • Themes
    Themes change the visual appearance of Firefox. Some themes simply change the toolbar's background colors; other themes make Firefox look like a completely different program.
  • Plugins
    A plugin is a piece of software that manage internet content that Firefox is not designed to process. These usually include patented formats for video, audio, online games, presentations, and more. Plugins are created and distributed by other companies.

To view which add-ons you have installed, open the Tools menu and select Add-ons, which will open the Add-ons window.
