Firefox will not start and will not uninstall. It's just dead.

Firefox will not open at all.

I have tried the Windows Uninstall, and the Firefox Uninstall Helper and can't get them to run.

It seems all the answers about how to fix problems in Firefox start with a Firefox window open, which is useless to me since I can't get it to do anything!!!!

Please help!

Install over firefox, you will not lose bookmarks and history.

I tried installing over it also, and the install won't run either.

Go to C:\Program Files\Mozilla Firefox and load firefox.exe does it work now?

I take it back! I reinstalled it from the downloaded file and it worked. THANKS!
