You can install a limited number of extensions from the Recommended Extensions program to add features to Firefox for Android. This article explains how to find, install and manage these extensions.

We are working to continuously add supported add-ons to Firefox for Android, see supported extensions here.

How do I update, change options or remove add-ons?

Expanded extension support in Firefox for Android Nightly

If using Firefox for Android Nightly you are able to install any extension listed on addons.mozilla.org (AMO) in Nightly.

This override was created for extension developers and advanced users who are interested in testing for compatibility, so it’s not easily accessible. Learn more about how to enable general extension support setting in Nightly.

Will more extensions be supported in the future?

We would like to enable support for more extensions on the new Firefox for Android experience and we are currently evaluating ways we can do so without introducing the compatibility and security issues from the previous version of our mobile browser for Android. We'll provide updates as soon as we have more details.

How do I change the theme of my Firefox for Android browser?

Due to the different user interface (UI) of the new Firefox for Android, only a limited number of pre-installed themes are available. See Using Dark Theme in Firefox for Android to learn more.
