Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences. - which you would rather avoid, I understand. However, the old profile is left alone, so you can reactivate it.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Let us know, if this fixes the problem.

Thank you.

It didn't work.

Oh wait, yes it does. I'm a dumb-dumb. Thank you!

Did you previously tried Safe Mode to check if one of the extension did cause your problem?
