This page is the place to learn how to start contributing to Mozilla mobile projects. The current products on mobile are Firefox and Focus, on both Android and iOS.
Firefox and Focus are developed by the Mozilla community. We hope this page will help you become an active member of our community! If you're looking for other ways to contribute to Mozilla, have a look at Mozilla's global page for new contributors. Either way, you should also take a look at the Mozilla Community Participation Guidelines.
If you still feel that you don't know where to start after reading this page, feel free to ping us on IRC. We're always looking for ways to improve this page to make it easier to start contributing. Suggestions and general feedback are more than welcome.

Setting up a development environment for Mobile Firefox is relatively easy! All the projects have repos and either a setup script or can built in an IDE.
Before starting to work on a bug, you should make sure you have your development environment set up. When you're ready to start hacking, it's a good idea to add a comment to the bug report letting the mentor know that you want to work on it. Ideally, the bug report should already have relevant source code links to help you get started. If you're unsure whether to take a certain bug or not, you can always contact us for clarification. If the bug you're working on involves UI changes, request feedback from the UX team (see contact list below) before landing.
For Firefox for iOS, you should follow the instructions in the Firefox for iOS github repo.
For Firefox for Android, follow our build instructions and you'll be ready to start hacking. Unfortunately, Firefox for Android is more complicated than a basic Android app, so we recommend that you're comfortable using a command line before getting started.
While you're waiting for your build, you can also take a look at our suggested workflow page.

If you are looking for a bug on Firefox for Android with guidance, we maintain a set of introductory bugs to help get you started! We have a tag called "good first bug" that are accessible for new contributors and will help you get familiar with the code review and landing process.
On Bugzilla, good beginner bugs are marked with an assigned mentor (see "Whiteboard" field). The mentor will help you get the necessary information to understand the issue, point out relevant parts of the code to look at, etc.
There are some whiteboard tags we use to characterize introductory bugs. Click the links below to see the list of those bugs!
You can browse these bugs on Bugs Ahoy!
