Firefox Project

The goal of the Firefox project is to produce a best of breed web browser for a variety of platforms, with a focus on usability and conformance to open standards.

Introduction

Firefox is an Open Source browser project. As part of Mozilla, Firefox contributors do their part to preserve choice and innovation on the Internet by offering competitive software for everyone.

Getting Involved

Help build the next generation web browsing experience. There are several ways you can get involved:

Mailing Lists - help shape the design of future browser releases.
Contribute Code - implement new features or fix bugs.
Test and QA - improve quality just by browsing.
Localization - help bring Firefox to other languages

The easiest way to start out is to subscribe to the email lists and join the discussions. You can also implement new features and fix bugs, or contribute to a localization project. Or you can help improve Firefox by just running testing builds every day, reporting crashes and bugs that you come across.
