Try to start Firefox in Safe Mode by holding down the Shift/Options key to see if that helps.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.


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