Firefox often shows black screen no matter which website I am using. For few minutes it hangs and then shows not responding. Later after few more minutes it crashes.

I am using windows 7, 4 GB RAM, Video drivers are up to date.

Did refresh firefox and restarted with Add-ons disabled many times. Nothing works. Please help

CPU usage is 45% to 55% and memory usage is greater than 999,999K

The crashes seem to be about JavaScript.

You can check for issues caused by plugins and set plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page.

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.


Do a malware check with several malware scanning programs on the Windows computer.

Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

Did you try to set all plugins to "Ask to Activate"?

Plugins are not affected by Firefox Safe Mode and will likely be activated automatically in a new profile.

Yes, I set all plugins to "Ask to activate". After every step I used firefox for 30 minutes and every time it gave the same problem

Firefox is still crashing, getting black screens, not responding, etc., and there is no proper solution yet. Running full scan with malwarebytes, avast, zonealarm, and spybot twice a week. Till now I did not find anything, not even a single suspicious file in my PC. But also the crashing won't stop. Deleted my complete profile from PC and created new one. Uninstalled firefox and deleted each and every file associated with firefox in entire PC. Removed all registry entries as well. Graphic drivers are also up to date. Is there any solution for this crashing, not responding, black screens, hangs, etc., ?

Are you using multi-process (e10s) tabs in Firefox?

Is browser.tabs.remote.autostart set to false (default) on the about:config page?


Create a new profile as a test to check if your current profile is causing the problem.
