Safari 14 does not work
Regretfully I upgraded to Safari 14 today and now youtube videos freak out if you mouse over them. Video blacks out then if you are lucky it comes back, maybe repeats the last 5 or 10 seconds, but sometimes it just spins without loading.
How can I get back to the previous version?
