You tube videos wont play full screen. It says "your browser doesnt support full screen". I tried looking in about:permissions for youtube.com but there is NO option to enable full screen mode. What can I do?

Is that happening with YouTube videos that are embedded on a web page?

This is about the HTML5 media player and this player requires a special allowfullscreen="true" attribute in the outermost iframe for embedded videos.

The full screen permission has been removed from "Tools > Page Info" and has been replaced by the full screen API that displays a notification to make you aware of the switch to full screen mode.
