Description Kevin Brosnan :kbrosnan 2014-01-22 00:00:07 UTC

Screen shot showing fullscreen offset

Description of problem: HTML fullscreen is offset


Version-Release number of selected component (if applicable): 29a1 (Jan-17th build)


How reproducible: Any page that invokes the HTML fullscreen API - https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Using_full_screen_mode


Steps to Reproduce:
1. Open a video that Firefox can play back ex. http://videos-cdn.mozilla.net/brand/Mozilla_Firefox_Manifesto_v0.2_640.webm
2. Right click on the video
3. Select fullscreen

Actual results: Video plays in full screen however the video will be offset (I suspect that the offset is the Firefox toolbar height)


Expected results: Video plays full screen centered 

Additional info: There are plenty of other ways beside video to trigger HTML fullscreen. Mozilla's nightly does not have this problem.

This is also a problem for f11 or menu > view > fullscreen.

I can see it also when source browser is launched. "View Page Source" gives clipped source view.
