Ditto. It was working fine a couple of weeks ago. There are a lot of threads on this topic, but they're all several months/years old, and surely this must have more recent solutions. Making Safari 32-bit and opting in and out of HTML5 trial doesn't make a difference.

I found the solution, an updated one found on another thread that was no longer correct:
Safari > Preferences > Privacy > Details (to the right or 'Remove All Website Data') > do a search on 'youtube' > 'Remove All'.
Worked for me.

This is ridiculous. Video windows simply don't show up on many sites for me, i.e., MacMost. No problems in Firefox. I tried all the aforementioned solutions, trashed prefs, disabled extensions, repaired permissions, etc. No good. Safari is supposed to be THE superior browser. I hate the idea of going to Firefox, but I may have to. Safari isn't worth the grief. Any other solutions are wekcome.
