Firefox crashes on open after running Adobe flash

Question

I need to run Adobe flash for a support site I use for work. There was a flash update and ever since the update firefox crashes immediately when I open it. If I uninstall firefox, uninstall flash, reboot my pc, re-install firefox, then firefox will run. Once I re-install flash and go to the support site I need to visit, firefox will then crash whenever I open it. I've noticed that if I don't uninstall firefox and flash but go into firefox after a reboot it stays up, but once I go to the support site that requries flash firefox will then crash whenever I start it. I've tried older versions of flash and firefox but the resutls are same. Anyone have any ideas to help? I use IE for the support site that requires flash and it works ok.

HI artzmama,
In order to better understand the issue, a little investigation will have to be done.
*Are there any crash reports listed under the page about:crashes?
*Do you have any addons or apps installed in Firefox? If so, please try to open it without these installed.
