Comment 9 for bug 1336994

It turns out the bug of Full Screen automatically reverting to the built in display rather than the active/current display was caused by FireFox and does not occur in Chromium. Unfortunately I noticed it with a new laptop that had built in HDMI rather than the old laptop which had VGA and then a VGA to HDMI converter box but was NOT using FireFox. On top of that there was new Kernel versions, new Windows 7 with new Intel Rapid Storage Technology, new UEFI, new OROM, etc. etc.

The resuming from suspend is NOT a factor in mitigating the bug, I had just happened to have run Chromium rather than FireFox at that time.

I'm not suggesting Chromium is better than FireFox. They both have strengths and weaknesses. For example on Linux FireFox has superior scrolling and mouse control. OTH Google Chrome (don't know about Chromium) scrolls just as nicely in Windows as FireFox does in Linux.

I just retested in Kernel 3.17-rc6 and Firefox still switches to the built-in display when you select full screen while watching tv broadcasts in rt. com or aljazeera. com on the external TV.
