Whether you're technical or not at all, there's a contribution opportunity for you. It's easy to get started, and your efforts help to make Firefox better!

We are committed to providing a friendly, safe, and welcoming environment for all. Our participation guidelines set the standards for behavior in this community and all official Mozilla forums.

Whether you are a regular contributor or a newcomer, we welcome you. If you feel you have been or are being harassed or made uncomfortable by a community member, please contact Caitlin Neiman, Add-ons Community Manager, or the Mozilla Diversity & Inclusion team, immediately.

Contribute to the Add-ons Ecosystem

Create an Add-on

Add-ons for Firefox Desktop

To get started, check out this comprehensive tutorial. It contains documentation, tools and information on how to get in touch with other developers. Need suggestions on what to build? Here is a list of add-ons people have asked for.

Add-ons for Firefox for Android

As of Dec. 14, 2023, Firefox for Android supports extensions that developers flag as Android-compatible on AMO. For more information about developing extensions for Firefox for Android, see Firefox Extension Workshop.

Port Add-ons to Firefox

It's easy to port Chrome extensions to Firefox. Read this quick guide and happy porting!

Improve add-ons in Firefox

Contribute to the Add-on Manager in Firefox

The add-on manager is an integral part of the end-user's experience with addons.mozilla.org

Familiarize yourself with the on-boarding materials: Onboard to Firefox codebase
Pick a "Good First Bug" to work on

Contribute to the WebExtensions API

Good First Bugs

If you'd like to contribute to the WebExtensions API and are new to the Firefox code base, we recommend getting started with a good-first-bug.

Visit our WebExtensions Contribution Onramp to onboard to the code base and get started with a good-first bug.

You may also want to read this blog post for tips on how to contribute to the WebExtensions API.

Develop WebExtensions APIs

If you're experienced with Mozilla infrastructure and would like to develop WebExtensions APIs directly for Firefox, here is a list of approved APIs that you can start contributing to.

If you want to tinker with WebExtensions APIs without having to build Firefox, WebExtensions Experiments is for you!

If you simply want to request a WebExtensions API, please read this information before filing a bug.

Improve addons.mozilla.org (AMO)

Addons.mozilla.org, commonly known as "AMO" is Mozilla's official site for developers to list add-ons, and for users to discover them.

Contribute code to AMO server

If you're new to Mozilla, and you know Python, get onboarded here and work on a "Good First Bug"!

Contribute code to AMO front-end

If you're interested in JavaScript and front-end technologies such as React and Redux, take a look at "Good First Bugs" in the front-end repository.

Become an Add-on Reviewer

Volunteer reviewers ensure the security and reliability of add-ons on AMO by testing submissions. Learn how you can join this community.

Rate your favorite add-ons

Search for your favorite add-on at https://addons.mozilla.org. On the add-on's detail page, scroll down to the Reviews section and leave a comment for the developer.

Create a collection

Collections make it easy to keep track of favorite add-ons and share your perfectly customized browser with others. Get started here.

Create a theme

Themes let you personalize the look of your Firefox. To create your own, start here.

Join the Recommended Extensions Community Board

The Recommended Extensions Community Board is comprised of a small group of community members who help with the ongoing evaluation of new and current Recommended Extensions and other special projects. Every board serves for six months, then a new group of community curators take over. Check the Add-ons Blog to learn when the next application period opens and for application instructions.

Curate Featured Themes collection

Help us curate Mozilla's Featured Themes collection to help users find high-quality themes. Learn more and apply to be a curator.

Contribute to add-on developer tools

Web-Ext is a tool for developing WebExtensions. Check out the contributing guide to get started.

The add-ons linter checks for errors and validates extensions submitted to addons.mozilla.org. Check out the contributing guide to get started.

Webextensions-polyfill is a library designed to help developers create extensions that are compatible across multiple browsers. See the contributing guide for how to get started.

Help add-on users

Answer questions from add-on users in the Firefox Support Forum!

Help add-on developers

If you're already familiar with add-on development or you think you're a good technical writer, help us improve the WebExtensions API reference documentation on MDN or the Firefox-specific documentation for add-on developers on Extension Workshop. The list of open issues for Extension Workshop can be found on in the extension-workshop repository on Github.

You can also help by translating docs on MDN to a different language (pro tip: try replacing the en-US part of the link above to your native language code).

Localization

MDN's "localization priorities" list - We're always in need of translators--here are the priority projects for add-ons
Localize addons.mozilla.org - Join Pontoon and translate addons.mozilla.org frontend or backend to your Language.

Contributor Recognition

Report Your Contributions

We want to make sure you're recognized for your contributions!

Create a Mozillians profile if you haven't already.
Add your name and accomplishments on the Recognition wiki page (please be specific--these will be archived by month, so list your recent contributions).

We regularly choose an outstanding contributor (Friend of Add-ons) and send that person a token of appreciation. Any contribution is eligible--it doesn't have to be an opportunity listed on this page!

Friends of Add-ons

Big thanks to these outstanding volunteer contributors!
