Firefox crashes afther an update. Dont know what update it was but it came up yesterday.

Ever since afther reapetetly reinstalled it still crashes before start up. It cant even start in safe-mode.

Tried to reinstall ver 18. It worked until new start-up of computer. Now it is the same.

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.
