Firefox 29 bug triage team

Hello! If you'd like to help out with bug management for Firefox 29 builds, please email bugmaster@mozilla.com!

Every night the latest pre-release version of Firefox is made available as the Nightly release. After 6 weeks of further development that branch becomes the Aurora release, and is more stable than the nightly; 6 weeks later it becomes the Beta release. If you want to test against the Firefox 29 release of Firefox, 29 download the Firefox 29 build and use it as your main browser. If you find any bugs, file them. (How to File a Bug).

You may also be interested in looking at the bugs others have filed, and see if you can replicate them or add any useful information. Triaging the Firefox 29 bugs will help us catch important bugs quickly, while you still have a relatively stable development browser to use!

1. Download the Firefox 29 build and run it.
2. Make a bugzilla account.
3. Skim over the current bugs against the Firefox 29 release (currently, the 29 branch).
4. File bugs when you find them...
5. Triage through the list of untriaged Firefox 29 bugs. So helpful!

Note: I would love to figure out how to make a mediawiki-bugzilla chart here to show bugs that have changed state from UNCO to NEW. Or since that may not be super useful, this might be better done in a dashboard; it would be good to know the number of bugs that changed state in this way.
