Youtube's HTML 5 player freezes all the time, how do I disable that and force flash on Safari I hate Flash but Youtube's HTML5 player stinks on Safari.

See this video it freezes all the time on Safari (El Cap). I watch movies from this guy, almost every movie he posts freezes on Safari. It is annoying as hell.

Any way to solve that?
Just download YouTube App from App store. It runs better when you watch videos on YouTube official App.
