Add-ons let you add bells and whistles to Firefox. You can get add-ons that compare prices, check the weather, change the look of Firefox, listen to music, or even update your Facebook profile. This article covers the different types of add-ons available and how to find and install them.

  • 1 What types of add-ons can I install?
    • 1.1 Viewing and managing your installed add-ons
  • 2 How do I find and install add-ons?
  • 3 Troubleshooting add-ons
    • 3.1 Problems with installing or uninstalling add-ons
    • 3.2 Problems caused by add-ons

These general types of add-ons can be installed:

  • Extensions
    Extensions add new features to Firefox or modify existing ones. There are extensions that allow you to block advertisem*nts, download videos from websites, integrate Firefox with websites like Facebook or Twitter, and add features included in other browsers, such as translators.
  • Themes
    Themes can decorate the menu bar and tab strip with a background image. Firefox also includes built-in themes. For more information on built-in themes, see Built-in themes in Firefox - alternative to complete themes.
  • Plugins
    Firefox automatically downloads and installs the Google Widevine CDM for watching Digital Rights Management (DRM) controlled content and an OpenH264 plugin for video calls.
  • Dictionaries
    Firefox can check your spelling, but not all locales come with a dictionary installed due to licensing reasons. You can find and install a dictionary for your language. (To change the language of the Firefox user interface, see the article Use Firefox in another language.)
  • Search engines
    Firefox comes with a number of search engines already installed. You can access them from the Search bar (if enabled) or directly from the address bar. If you want additional search engines, you can install them on the websites directly or from addons.mozilla.org.

Viewing and managing your installed add-ons

Search engines can be viewed and managed in the Search panel in Firefox Settings. For other add-ons:

  1. Click the menu button Find and install add-ons to add features to Firefox (4) and choose Add-ons and themes. The Add-ons Manager tab will open.
  2. Select the panel for the type of add-on you wish to view or manage, such as the Extensions or Themes panel.

For detailed information on disabling or removing add-ons, see Disable or remove Add-ons.

Here is an overview to get you started:

  1. Firefox may offer personalized recommendations. Click the menu button Find and install add-ons to add features to Firefox (5), click Add-ons and themes and select Recommendations.
  2. To install a recommended add-on, click the blue + Install Theme or + Add to Firefox button, depending on the type of add-on.

At the bottom of the list of recommended add-ons, there's also a Find more add-ons button you can click. It will take you to addons.mozilla.org where you can search for specific add-ons.

For advanced users: You can also install add-ons from a file. If you saved the installer file to your computer, (for example, an .xpi or .jar file) you can install the add-on using the gear icon Find and install add-ons to add features to Firefox (6) in the upper-right area of the Add-ons Manager Extensions panel. Select Install Add-on from file... from the menu, then find and select the file.

Some extensions place a button in the toolbar after installation. You can remove those or move them into the menu if you want - see Customize Firefox controls, buttons and toolbars.
