Script doesn't work with Firefox 4

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Firefox 4 Beta 11 and Greasemonkey from addons.mozilla.org (v 0.9.1)
2. Install YT-HD Script (doesn't matter if you use the stable version from 
userscripts.org or from code.google.com)
3. Open a YT Video

What is the expected output?
The script should work the same than in Firefox 3.6.13 I had installed before 
and it is still working in a Portable 3.6.13 with the old firefox-profile.

What do you see instead?
The player is a black box and you can't see the video, but you can hear the 
sound and control the player when you klick where the controls should be. 
Viewing the Vid in fulscreen also works (when you don't miss the "invisible" 
fullscreen-button).
If you click on the script settings the title of the button changes to "hide" 
but no Window appears and when you click again nothing happens and it stays by 
"hide".

debug String not aviable because of the bug in opening the Settings.

I tried it with the install version on my Notebook with some other Add-Ons 
installed and with a vanilla portable version which only has greasemonkey and 
this script installed.
Flash-Version is 10,2,152,26

Same happen in Firefox 5 Beta 2.

It would be awesomecakes if you could fix it somehow (yeah, lots of people said 
it before), I'd even pay for it :s
