Developers can help Mozilla by fixing bugs, adding new features, writing tests, updating documentation, making Mozilla technology smaller and faster, and making Mozilla development easier for others.

For Testers

Our products are what they are because of the help of people just like you who use them day to day, reporting bugs and helping us improve quality. To get involved, read about how you can help to test Mozilla.

Nightly Builds: the Bleeding Edge

Created most weekdays from the previous day's work, these builds may or may not work. Use them to verify that a bug you're tracking has been fixed.

We make nightly builds for testing only. We write code and post the results right away so people like you can join our testing process and report bugs. You will find bugs, and lots of them. Mozilla might crash on startup. It might delete all your files and cause your computer to burst into flames. Don't bother downloading nightly builds if you're unwilling to put up with problems.

• Mirrors
• Mozilla Firefox: Windows, Linux (gtk2, i686), Linux (gtk2, x86_64), Mac OS X, etc, localized builds.
• Mozilla Thunderbird: Windows, Linux (gtk2), Mac OS X, localized builds.
• SeaMonkey: Windows, Linux (gtk2, i686), Linux (gtk2, x86_64), Mac OS X, localized builds.
• Camino: Mac OS X.

How To Get In Touch With Mozilla Developers

You can find many Mozilla (and Firefox, Thunderbird, Camino, SeaMonkey, etc.) developers on IRC. You can talk with them in real time by logging on mozilla.org's chat server, irc.mozilla.org with an IRC client. Mozilla suite and SeaMonkey come bundled with a chat client, ChatZilla, which is available for Firefox as an extension.

We also host developer forums, which are available through both mailing list and newsgroup interfaces.

And of course, most focused technical discussion happens in Bugzilla, our bug-tracking system.

For Hackers

Build Mozilla

Get the Source, then Build It.
