Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Jonathan Rawle]

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9.2.15) Gecko/20110318 Red 

The taskbar panel in KDE3 remains visible during a fullscreen Flash video. This happens every time except for the first time fullscreen is used after Firefox is started. Every subsequent time, the panel will be visible in fullscreen mode until Firefox is restarted.

This happens with both Firefox 3 and Firefox 4, and with Flash 10.2 and 10.3 Beta, both with and without hardware acceleration.

This behaviour is not seen with any other browser - the taskbar is hidden correctly. Switching Firefox to fullscreen mode (F11) before setting the Flash video to fullscreen does not make any difference.

This happens for all video sites: Youtube, BBC, etc.

Reproducible: Always

Steps to Reproduce:
1. Start Firefox
2. Start watching a Youtube video and click the fullscreen button - works as expected
3. Return to windowed mode, then go to fullscreen again
Actual Results:  
The fullscreen video will display with the KDE3 taskbar visible on screen

Expected Results:  
The KDE3 taskbar will not be visible in fullscreen Flash mode

We're in the process of removing support for plugins (bug 1677160), so I think this bug is irrelevant now.
