Windows 7 Firefox Testing
This project is for those individuals who are interested in ongoing testing of Firefox using Windows 7.
Improving Litmus
Litmus is our online test case management tool for manual test cases. We'd like to start a project to redesign the tool around the current needs of the disparate teams that use it. To do that we invite your feedback and your help. Everyone is welcome to join this project and help out. If you join the project, then you'll get special notices about progress, design reviews, design brainstorming sessions, and proof-of-concept availability.
