Full screen returns to regular size when focus is lost
I have two monitors. When I open FF in the second one and play video in fullscreen mode in FF, two possivble variants are possible: 1) Either the fullscreen appears on my first screen (usuallu when tyhe Adobe flash player is used), or 2) the fullscreen returns to original size when the focus is anywhere else.
With Chrome, everything works well.
My system: Kubuntu 14.10, 32 bit, Firefox 36.0.1

If you use flash for youtube videos try: https://addons.mozilla.org/en-US/fire.../flash-game-maximizer/ Else as far as I have tested, this does not happen with the HTML5 player.
