Website Testing

The Website Testing project gives our community a way to actively participate in testing major websites around the world. Since the primary focus of web browsers are parsing all different kinds of web pages and applications, the project can help to make Firefox more stable and functional.
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.
