Firefox crashes when playing video in full screen

more options

Hi all, my firefox on windows 7 just updated to v84 and I am having some trouble playing videos in full screen. When I play videos on youtube AND other platforms in full screen, firefox just freezes(while still playing audio) and then crashes. I tried restarting without add-ons and reinstalling firefox, no luck. However, under windows' safe mode everything is just fine. Any solutions please? Thanks in advance :D

There might be an issue with your system drivers , check if there are any updates available to the drivers and try playing videos
