Firefox won't startup after Windows7 update week of June 4, 2010
After updating Windows 7 last week with all the security updates, both Firefox 3.6.3 and 3.6.4 Beta wouldn't launch even after I un-installed each, cleaned the registry, downloaded the latest builds and re-installed.
Every time Firefox opened
Windows 7 was updated on weekly normal update
