As new folks join the QA team and old timers continue to test on Vista... we should all get a better understanding of some of the incompatibility issues with Firefox.
One of the most critical pieces impacted by changes in Vista vs XP is Firefox software update. Although we have a good idea what works, we don't all know what doesn't or why that is. In order to help QA and Seth (and other devs) figure it all out, I have put together a matrix of tests that we should try to fill in.
