No Flash Player in Firefox as of today
For Youtube change to HTML5 video player here:
https://www.youtube.com/html5
Add more sites you’ve needed to edit video preferences for if you wish.
Thanks! 
Hey, thanks so much for that heads up, HowlingUlf. Man I hate the forced frequent foolish friggin Adobe updates.
The non-youtube sites … I wonder if they will start dropping Flash and supporting HTML5 also.
