Install Firefox, runs fine. Restart computer, Firefox will not start or finally when it tries to start script errors occur. If I reinstall Firefox after a computer restart, it will work fine, again when the computer is shut down the next time it is started, will not be able to use Firefox. Firefox will not start up in Firefox safe mode, will not start in windows safe mode. Not add on's, nothing added, just the Firefox installer Performed complete system restore on the computer, same problem. Windows 7 Pro. Remove Firefox from windows control panel, restart computer, install firefox, will run. turn off computer, turn on computer, firefox will not start or freezes. I am interfacing the internet via Explorer now.

I have reinstalled Firefox so it will run in order to perform the steps requested below.

Try this

Open TaskManager, if it running firefox.exe > end all processes


Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Thank you iamjayakumars. I have performed a complete system restore. The problem I described is after the restore. After trying to start firefox, task manager does not show firefox running. After starting firefox and waiting a very long time to see what happens, a script error occured. After a couple of times trying the wait game, a type of script error was shown. I found this link on support, seems to be what is happening, but as you see that fix did not help either.
