Embedded Video from Vimeo or youtube no play in fullscreen

I just found out that using the new iMac Retina 5k the full screen videos from youtube or Vimeo do not play, when you use the embedded player. Only directly from youtube or Vimeo they do play. Same with chrome or Safari works fine. So what problem has Firefox?
