Finally fed up with the buggy Adobe Flash, all of youtube is
going to HTML5 instead. Chrome already has it, IE has it, and
Firefox beta version is adding it.
Quote:
"GOOGLE'S YOUTUBE video portal has made the switch to HTML5 as a default renderer, marking yet another milestone in the downfall of the Adobe Flash format.
Historically, Adobe Flash has been the renderer of choice despite its buggy limitations because it offered a number of tangible benefits over early HTML5 implementations.
However, from today, Chrome, Internet Explorer 11, Safari 8 and beta versions of Firefox will move over to the much-improved HTML5 standard."
