Test Pilot is a platform aimed at collecting structured user feedback from Firefox and other Mozilla Labs experiments. As a Test pilot, not only will you try before anyone else the newest features and coolest user-interface ideas, you could also learn how those test results may contribute to future designs. The goal for this platform is to encourage everyone from all skill levels to improve the Web experience by participating in these tests.

Once you install the Test Pilot add-on, you will automatically receive notifications on upcoming and finished tests. You will have the option to quit tests or leave the platform. If the test requires you to install a new feature or product, the platform will ask for your permission.

When a product is not easy to use, don't just wonder why it's designed that way. Make your mark on the design and help us improve it! Join the forces, we want you!
