Description mikey 2016-08-14 08:46:24 UTC
Description of problem:

Watching youtube in full screen works for a few seconds (to a minute) but after that you are dropped back to the Firefox window. Clicking full screen again just repeats the experience.

Version-Release number of selected component (if applicable):

My current version of Firefox is: 

Name        : firefox
Arch        : x86_64
Epoch       : 0
Version     : 48.0
Release     : 5.fc24
Size        : 133 M
Repo        : @System
From repo   : updates

Gnome Version 3.20.2

How reproducible:

Always reproducible.

Steps to Reproduce:
1. Open Firefox (tested in Gnome Shell)
2. Navigate to a YouTube and play a video
3. Select fullscreen
4. Wait a minute until fullscreen exits

Actual results:

Fullscreen starts and is dropped after a few seconds.

Expected results:

Fullscreen remains until deselected.

Additional info:

I have seen this behavior for quite some time on Fedora. It was definitely happening the last release (23) and possibly the one before that as well.

Hmmmm.. Just tested in Firefox safe mode and it seems to be working properly, so I guess it's plugin related.

Looks to be down to "Unload Tab" plugin, which was broken anyway.
