Been having trouble for some time with Firefox crashing in the middle of sending emails. Downloaded Vers 4 with a hope this would stop. This haven't and today Firefox has crashed some 4-5 times in less than 1 hour. Rebooting PC doesn't help. Following latest crash Firefox will not load not even in safe mode. Now getting Windows msg Firefox has stopped working check online or close the program. Check online gives the msg application failed to initialise properly - click ok to terminate. Have also had a mge stating that Windows DEP (Data Execution Prevention) has seen that Firefox may be a virus or a security threat and that it's attempting to run a program from memory restricted for use by other programs. See DEP in Windows help. unsafe and has closed the program

In the URL field, type: about:crashes and hit Enter. Then choose the most recent crash (they're links, so click them). You may possibly find some insight into the problem.
