hi, thanks for providing a crash report id. this may be an issue caused by your norton security software that is hooking into firefox and causing it to crash (maybe through a program/signature update done by them). can you please try to disable norton temporarily and see if you can get firefox to launch again & please also get in contact with their support...

Thanks Fred.... We checked and issue is definition update related to Symentec. Thanks for the support.

Cheers,

Meedstone
