(Core :: Audio/Video, defect)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:17.0) Gecko/17.0 Firefox/17.0
Build ID: 20121023124120

Steps to reproduce:

1) I went to http://youtube.com/html5 and joined the HTML5 trial
2) I went to http://www.youtube.com/watch?v=JGPO9-7dJZA (or any other HTML5-enabled video on YouTube).
3) I clicked the fullscreen button (on the bottom-right of the video player).


Actual results:

Firefox went into the Lion-native fullscreen mode with part of the upper UI visible (see screenshot).


Expected results:

If Firefox plans to keep using native Lion's fullscreen view for such things, it shouldn't leave parts of UI visible.

I experience the bug in safe mode, too. Unfortunately, I can't reproduce it in Aurora - is it fixed or are there any other possible causes related to my profile files?

Comment 2

[Virgil Dicu [:virgil] [QA]]

If it occurs in 17 and not in Aurora, then the fix is likely not ported in Beta.

I can see the UI for a second while the video switches to full screen. Is that the same behavior you are seeing or is it more persistent on your side?

I can reproduce this up to Nightly.

It's persistent.

Actually, it's not only HTML5 video fullscreen, it's happening each time I enter fullscreen mode using the JavaScrpipt fullscreen API. I'm attaching a screenshot of what's happening when I click the lower-right button on http://pracowniaedukacji.ee/ which causes the browser to enter the fullscreen mode using this API.

Changing bug's title to reflect my last comment. Also, see:

Michał, did you test Aurora (comment 1) using the same profile or a different one?

If the same profile shows better results in Aurora then in Beta, the issue was likely fixed after Beta, and there's no point in keeping this bug open.

[Michał Gołębiowski-Owczarek [:mgol]]

I tried using new profiles before... I've re-tried copying my default profile first and running Aurora and Nightly on a new profile. The issue exists in Nightly, even though I run this copied profile in safe mode.

Comment 8

[Michał Gołębiowski-Owczarek [:mgol]]

OK, I've nailed it down... The problem exists when I use a non-default motive. I use this one normally:

I've tried with a different profile and the issue appears, too.

Comment 9

[Michał Gołębiowski-Owczarek [:mgol]]

I meant, a different motive, not profile (although I've tried on a fresh profile and I was able to reproduce the bug after changing the motive).

Sorry for excessive comments.

I can confirm this issue on Firefox 18 beta 1. The bottom part of the navigation bar is left behind while the video is in full screen mode.

Steps to reproduce:
1. Launch Firefox with a new profile
2. Navigate to https://addons.mozilla.org/en-US/firefox/personas/ and install one of the personas
3. Navigate to Youtube and enable html5 trial: http://youtube.com/html5 
4. Play a video of your choice that uses HTML and click on the Full Screen button.

Expected results:
The video properly enters Full Screen.

Actual results:
The bottom part of the navigation bar is left behind while the video is in full screen mode.

Is the component really video/audio? It happens on every mozRequestFullScreen invocation, not only in HTML5 video.

Comment 12

This probably belongs to either Firefox:Theme or Core:Widget cocoa, see also bug 716450. I see this on 10.7 too.

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

If this is still an issue -- can you check with latest nightly, now that bug 1071821 is fixed?

Comment 14

[Michał Gołębiowski-Owczarek [:mgol]]

I'm no longer on OS X 10.8, I use Yosemite beta (10.10) now. There, I cannot reproduce this issue on nightly but I also can't do it on stable so this might be an OS-related change.

Sorry, I don't have access to OS X 10.8 now to re-test it.
