With this addon you can play almost any video on YouTube and many videos on Vimeo as a HTML5 video. This includes videos with monetization enabled which normally don't play in the html5 player.
With standard settings, videos are automatically loaded in the HTML5 player.
Features:
* Select different methods to force the HTML5 player
* Change the size of the video player (manually or automatically)
* Disable Flash only on YouTube
* Disable the YouTube SPF function (active by default)
