Add-ons for Firefox for Android
Firefox for Android supports add-ons using the same extension system used by all other Gecko-based applications. Get started here.
Improve add-ons in Firefox
WebExtensions is the new API for building add-ons in Firefox. It seeks to unify the extension APIs and architecture with those of other browsers in the name of interoperability and modern architecture.
Help Develop Web Extensions APIs
We need your help extending the APIs to support the needs of add-on developers. To get started, please onramp to the Firefox codebase by following this process.
- Pick a good first bug from this list.
- More ways to hack
Tell us which WebExtensions APIs you need
- Take this survey to help us prioritize available WebExtension APIs.
Command Line Tool
We're working on a command line tool to help build, run, and test web extensions. Contribute to this project here.
More Ways to Get Involved and Get Help
If you need help or have ideas, please go to the add-ons forum, or the #webextensions channel on irc.mozilla.org.
Please join the dev-addons mailing list to find out the latest news and contribution opportunities.
