Download Firefox For All languages And Systems {web link} Save the file. Then;

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder. Linux: Check your user manual.

• Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory.


Look for, and rename any Mozilla or Firefox folders by adding .old to them.

After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.

Follow the instructions to create a new, blank profile. Use is as is without changing anything. Is the problem still there?

https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles Windows: 32-bit C:\Program Files\Mozilla Firefox\firefox.exe -p 64-bit C:\Program Files (x86)\Mozilla Firefox\firefox.exe -p Mac: Navigate to /Applications/Utilities. Open the Terminal application. In the Terminal application, enter the following: /Applications/Firefox.app/Contents/MacOS/firefox-bin -p Linux: In Terminal run: firefox –P For users who have one or more builds from mozilla.org this will not work. It would be best to have the full path so if you had placed the untared contents in a folder in /home it would be /home/<username>/foldername/firefox/firefox –P An easy way would be not to do it in a terminal but in say a launcher since you have to point it to the firefox script in Firefox folder you can then add –P on end. You can also have the exact "profilename" after the -P so Firefox will start with that Profile.

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

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

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

in safe mode no error. Appearance -> theme is disabled. I never changed it

Do you have any add-ons installed? It could be one of them.

As a test, disable your protection programs.


Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Restart Firefox. Are there any problems?
