After upgrading firefox to 6.0.2 firefox crashes upon opening. When I try to open firefox the "Mozilla Crash Reporter" opens up. I tried all the sugestions on the support page. None of these worked. It will open with the computer in safe mode. I can not find where to start firefox in safe mode after upgrading.

I can open it now after running firefox in compatibility mode for windows XP sp2. The problem with this is I have to accept permission everytime I open firefox. If I change user account control settings to not ask every time firefox crashes on opening again.
