FireFox Has Stopped Working

For the first month or so when I got firefox it ran fine, now as soon as I click the firefox icon on my desktop or on my start menu it instantly says FireFox has stopped working without even making a attempt to open! I have searched everywhere Google, Youtube Videos, but none of them work or help my problem also I have also noticed that all of the error messages in videos or other questions that have the "same" problem come AFTER they open firefox everything I saw on how to fix it never worked for me Because they all had a different problem that did not apply to mine.

Re: FireFox Has Stopped Working

None of your browsers work correctly any more? Two thoughts:

(1) Do you have a program control firewall that is blocking your browsers because they've updated? This article has more of a discussion of that possibility: Firefox can't load websites but other browsers can.

(2) Is it possible you are infected with malware? You may want to run some supplemental scans. These three tools are highly regarded (and free):

Try to reset Firefox. If that doesn't work, then try to re-install it, but try to install it from some other place than what you did the first time, because it might be a link-rot.

Actually, you should never install Firefox from any place but mozilla.org:

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

That is a good point, a place you can trust.

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.
