Firefox will not open unless I run it in compatibility mode (Windows XP SP 3), run it as an administrator, or launch it immediately after a reinstall (the reinstall thing only works once.) How do I fix this?

This morning, Firefox crashed. After this, when I click the Firefox icon, the hourglass appears and then nothing happens. Firefox does briefly appear in the task manager when I do this.

I tried rebooting. I tried reinstalling multiple times. (Firefox will run when I select "Launch Firefox" from the installer. Then the problem occurs again.) I tried safe mode. I have found that Firefox will work if I select Windows XP compatibility mode from the icon properties menu or if I run the program as an administrator. When I do this, Windows asks me if I want a program to be able to make changes to my computer.

I have noticed that a Windows Error Report is being generated each time Firefox will not open.
