This is strange. You can delete those configurations or you can reset Firefox if it stays open long enough for you to navigate to the about:support page. However if they are there for functionality, you can try to Use Troubleshoot Mode in Firefox and make sure all the addons and extensions you have are up to date.

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

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.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

  • If you have many extensions then first enable half of the extensions to test which half has the problem.
  • Continue to divide the bad half that still has the issue until you find which one is causing it.

You can delete the prefs.js file to reset all prefs to the default value or only remove these lines from the prefs.js file.
