Firefox stopped working

more options

Firefox has stopped working. I've deleted and reinstalled, I've tried to make it work in trouble mode, but it keeps freezing up. Recently updated OS security fixes. Invariably, I get the circle of death if I try to clear history via the application menu, and it stops responding. The same thing happens when I try any of the drop-down menus on the menu bar.

Slerch,

Hopefully someone can help you but they may need more information. I run Webroot SecureAnywhere and, after a Firefox update, I have to update "Application Protection" setting the Firefox.exe application from Protect to Allow.

That is JUST an example of what cause some of the issues you are having. Try checking your anti-malware applications in case they are preventing issues. Since I run Firefox in Sandboxie, special update instructions must be followed! I created a thread with instructions that work but have not been updated because it seem no one was needing it.
