SUMMARY
presentation mode sometimes fails to prevent the screen from dimming.  in my case it sometimes happens when watching a youtube vid in firefox, also when actually turning on presentation mode instead of letting firefox enforce it, it still does not prevent the screen from dimming 


STEPS TO REPRODUCE
1. open firefox
2. go to youtube
3. play/watch a video

OBSERVED RESULT
presentation mode is enforced by firefox however, the screen still dims after the specified amount of time for it to dim. 

EXPECTED RESULT
presentation mode is enforced by firefox and thus, the screen does not dim.
