Firfox will no longer play ANY video
since the last update, my Macbook M1 firefox (89.0) will no longer play ANY video.
Amazon Prime, YouTube and Netflix. All fail with a spinning circle and a error message "please restart your device" or similar.
All sites play fine in C*rome
Any suggestions? I really don't want to have to use C*rome
I might add: i emptied my cache and ran in "troubleshooting mode" and neither made a difference
