After that, it will ask if you want to quit firefox or open it in safe mode. I just open it in safe mode. Close it, re-open it. Now it is normal. Does anyone know what the problem is and how to fix this? Thanks.

Funny, I was going to try this but after that day, this stop happening. I don't have this problem anymore and I didn't do anything. I don't know why this happened. Strange.

Try to start Firefox in Safe Mode by holding down the Shift (Mac: 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.
