Summary

There is a large discrepancy between the platform/hardware/driver configurations we see on Release versus what we see on our test branches. Additionally, the Graphics team and our testing community does not and can not provide sufficient test coverage to fill this gap. As a result we've historically been notified far too late about critical graphics issues triggering multiple chemspill releases and a loss of users.

In an effort to improve pre-release visibility of graphics regressions we have partnered with Betabreakers, a company that maintains a lab specifically designed to test various modern and legacy configurations of Windows versions, graphics hardware, and graphics drivers. We try to coordinate a graphics sanity testrun with them once per mozilla-aurora cycle, as detailed below.

More information about our relationship with Betabreakers can be found on mana.mozilla.org.
