Revision Content

Firefox is Mozilla's popular Web browser application, available for many platforms including GNU/Linux, Mac OS X and Windows on the desktop, as well as Android on mobile devices. With broad compatibility with the latest in Web technologies and powerful developer tools, Firefox is the greatest browser both for end users and Web developers.

Firefox is an open source project; much of the code is contributed by our enormous volunteer community. Here you'll learn both about contributing to the Firefox project, but you'll also find links to documentation about building Firefox add-ons, using the Firefox developer tools, and so forth.

Learn how to create add-ons for Firefox, how to develop and build Firefox itself, and how the internals of Firefox and its subprojects work.

  • Developer release notes

    Developer-focused release notes; learn what new capabilities for both Web sites and add-ons arrive in each version of Firefox.

  • Project documentation

    Get detailed information about the internals of Firefox and its build system, so you can find your way around in the code.

  • Developer guide

    Our developer guide provides details on how to get and compile the Firefox source code, how to find your way around, and how to contribute to the project.
