Firefox continues to stretch like it's going into fullscreen, going back, and then freezing entirely

I don't know quite how to explain the problem I keep having. After upgrading to 91.0 ESR, the problem I had with regular Firefox has happened once again. The problem I keep having is that the browser will stretch like it's going into Full Screen for a second, snap back, and then stretch up again before freezing and crashing entirely, that is, if it doesn't hold on the fake fullscreen and turn off my monitor, making me have to restart my PC entirely.

I also notice that this newest version freezes more than usual overall.

Can someone explain what the problem is and how to fix it, or if Mozilla's going to fix it in the next update?

Thank you!

Close Firefox. Open your file browser to this hidden location:

  • Mac: *~/Library/Application Support/Firefox/Profiles
  • Linux: *~/.mozilla/firefox/Profiles
  • Windows: %AppData%\Mozilla\Firefox\Profiles
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
  • Windows XP: C:\Documents and Settings\<user>\Application Data

\Mozilla\Firefox\Profiles\

Search for the above file. Then rename or delete it. Restart Firefox.
