1456079 - Allow usage of native macOS fullscreen mode for video playback

Status: RESOLVED DUPLICATE of bug 1403085

(Toolkit :: Video/Audio Controls, defect)

Description

[misc.ds]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180323154952

Steps to reproduce:

I watch HTML5 videos (mainly YouTube) in fullscreen on macOS.


Actual results:

Other than Safari Firefox does not use the native solution of creating a new space for the video, but covering the actual one with the video. Thus:
- I am not able to access the menubar by moving the cursor to the top of the screen.
- I am not able to access the dock by moving the cursor to the bottom of the screen.
- I am missing out on any notification while watching the video.
- I am not able to switch between my desktop and the video by using swipe gestures.


Expected results:

I guess, those problems could be solved by at least allowing the option to use native fullscreen mode for video playback on macOS.

I was able to reproduce this issue using latest Fx release, Beta and Nightly build. When running a youtube video in fullscreen I`m not able to access the menubar by moving the mouse to the top nor the dock by moving the mouse to the bottom. 

In Chrome I`m able to access either the menubar or the dock by moving the mouse.

I think the proper component would be Toolkit::Audio/Video Controls. Please change if this is not the right component.

I don't think 1403085 is a duplicate of this bug as it discusses native full screen for the browser window, not for video playback.

I have no problems with native full screen for the browser window.

No, it doesn't. See comment #1:

and comment 11 which applies also to your case:
