540719 - Full-screen video should appear on the same monitor as the originating window on multi-monitor setups

Status: RESOLVED WORKSFORME

(Toolkit :: Video/Audio Controls, defect)

Description

[(no longer active)]

STR:

1. Open an ogg video in a Firefox window on the non-primary monitor.
2. Switch it to full-screen.

The full-screen window appears on the primary monitor, whereas it should appear on the same (secondary) monitor.  Also, any interaction with the browser on the secondary window will close the full-screen window (which is kind of logical, but shouldn't be possible if the full-screen window opens in the same monitor.

The behavior of Flash movie on Youtube for example is opening the full-screen window in the same monitor as the browser window.

I haven't been able to reproduce this bug.

The steps that I followed:
0. I have three monitors set up in a [2][1][3] setup, where [1] is the primary monitor. I used this video to test: https://secure.wikimedia.org/wikipedia/commons/wiki/File:Bird_flock_at_Westerland,_Sylt.ogg

1. I moved the browser to maximized position on [3] and went full screen. The video went full screen on [3].
2. I moved the browser to maximized position on [2] and went full screen. The video went full screen on [2].
3. I moved the browser to maximized position on [1] and went full screen. The video went full screen on [1].
4. I moved the browser to non-maximized window on [3] and went full screen. 
The went full screen on [3], unless the top left corner of the browser was on [2] (in which case the video went full screen on [2]).
