Belatedly.... thanks for the help. I'll take a look at those solutions.

As to what specifically happened, it simply wouldn't expand to fullscreen mode. Just a blank black box around the normal size. Recently (html5 or youtube?) had been prompting me with a "deny" or "allow" button at the top. I always said allow which worked. The problem began early this week.

Thank you again.

Sought a fix online and it said to right click and change in html5 player, but can't find where to change.

Anyone know a fix for this issue?

Thanks!
