Problem solved, sorry for the noise.
In case one is interested in the solution: The flash setting menu only
works in full screen mode! Then it is possible to untick the box
"hardware acceleration". After that everything works.

Dear arch users,
I'm using arch linux x86_64 (kernel 2.6.38), Firefox 5.0 and the Adobe
Flash Plugin 10.3.162.29 64bit support (according to
http://www.adobe.com/software/flash/about/). My problem is that I can
view flash videos in Firefox in normal mode, but in full screen mode
the videos slow down (and the CPU usage rises much). A half year ago
everything worked fine, but after some updates it won't work anymore.
I also tried a kernel/firefox downgrade without success. I suspect
that it has to do with the hardware acceleration settings in the flash
menu (right click on flash video). Here hardware acceleration is
enabled and I can't disable it, since the mouse and keyboard simple
don't work on the flash settings menu.
Is there another way to disable hardware acceleration? Or any other
hints?
Thanks,
Benjamin
