Hello,

Which version of Firefox are you using? You can check by going to:

  • Help (or New Fx Menu > Help-29) > About Firefox

Did you download Firefox from the official Mozilla site? Sometimes if you search on Google or any search provider, they sometimes have "Advertised links" which are sometimes Firefox bundles that have been slightly modified.

If you did download from a different website and believe that to be the cause, you can report the link here:

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

  • Click the menu button New Fx Menu, click Help Help-29 and select Restart with Add-ons Disabled.

If Firefox is not running, you can start Firefox in Safe Mode as follows:

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.

When the Firefox Safe Mode window appears, select "Start in Safe Mode". Note: Make sure that you do not click "Reset Firefox" if you want to keep your extensions and settings.
Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.
