Google Play Music doesn't play in a "standalone" window. Tries to find a track, can't play it, then skips to the next one. When it reaches the end of the play list it displays the error message: "Can't reach Google Play". Works fine in standard firefox window. There's also a strange grey box in the bottom left corner, which doesn't appear in a standard firefox window. Google Play Books' interface works just fine.
