Status: RESOLVED WORKSFORME

Description

[Patrick]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release)
Build ID: 20130730113002

Steps to reproduce:

while in fullscreen mode on a website's video player (twitch, youtube, etc) when swiping to a different screen or app in Mac OSX 10.7.5, firefox will grab the screen back and close fullscreen mode


Actual results:

fullscreen mode closes and maintains focus of OSX


Expected results:

the swipe completes and firefox stays in fullscreen mode on it's own separate 'desktop'

This did not occur until my recent upgrade to Firefox v23.0

I created a new profile and still got the same result.
Swiping while in fullscreen mode snaps back to the firefox window with fullscreen mode ended.

Could you try using Firefox Safe Mode,too?

I've only tested this on Mac OS 10.8.4 and swiping while in fullscreen mode doesn't affect firefox window for me.

Patrick, I'm also unable to confirm this bug, using Mac OS 10.8.4 and Firefox 23.  I can open a video in full screen mode from YouTube, then swipe to a new desktop, where I am no longer in full screen mode or looking at Firefox; then swipe back to the desktop area with Firefox, where the video is still playing and still in fullscreen mode.     Are you able to reproduce this with your add-ons disabled?

I bet this could be a 10.7-issue.

I apologize about the delay in getting back to you.  This has after returning to my profile after testing with a fresh one.
