The Joys of Microsoft Software

I have a system with Windows XP installed. Firefox has been installed forever. About two weeks ago I upgraded to Firefox 4. It's been working great. Right up until April 14th, 2011, when Microsoft Patch KB2509553 was installed. After that was installed, running Firefox 4 would bluescreen instantly. I'm Sure It Was An Honest Mistake.
