Please try Firefox's safe mode. If that does not help try a clean reinstall. * [[Troubleshoot Firefox issues using Safe Mode]] Take Care <br />On a clean reinstall * do NOT remove the Firefox Profile * do NOT use any option that removes personal information *but DO remove the Firefox program files * see [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox]]_5-reinstall-firefox ----- For forum cross referencing purposes only. <br /> The Crash Report was not helpful.

Ya, the only portion of the crash that was helpful was the last thread: [http://msdn.microsoft.com/en-us/library/b6801kcy.aspx] which threw an exception. A value is the wrong type. And the signature is a memory location. What happened when you started Firefox in Safe Mode?
