In fact WinXP SP2 &amp; 3 are still supported by Mozilla for Firefox. I doubt if Mozilla support for Vista will end anytime in the near future.
</p><p>Overall, Mozilla doesn't select arbitrary dates for ending OS support, the last to fall by the wayside was Windows 2000 over the need by Mozilla to update the program that was used to put together Firefox. The newer version just didn't support Windows 2000 or WinXP and WinXP SP1.
