Test Pilot is an opt-in program that every firefox’s user can join to improve their experience by conducting or participating in usability related tests. The user only needs to install Test Pilot add-on, and he will receive the notice for upcoming tests. At the end of these experiments, the user can choose whether or not to submit his test data.
Few weeks ago Mozilla announced that Test Pilot program has reached more than one million users. This increase came after the add-on was included in Firefox beta 4 by default but shows that Firefox users want to get involved with Mozilla. This program allowed users to have a more active role in the community and share their ideas, likes and dislikes directly with developers.
It also is important to mention that all Test Pilot studies, resulting insights and aggregated data are shared under Creative Commons licenses for the benefit of the Open Source community.
