Opensuse 11.4 - Install flash player 64bit on Firefox 4 x86_64

Since I started using Firefox 4 beta x86_64 on OpenSuSE 11.3 I noticed that some flash players from different websites were not working properly. On some flash players or flash animations I had white rectangles appearing over images. I hoped that this would be fixed when Firefox 4 would be released or after I upgraded to OpenSuSE 11.4, but the problem persisted.
One solution for this flash player problem would be to uninstall the 64 bit version of Firefox and install the 32 bit version, but this would result in a decrease of speed for Firefox.
The second option is to uninstall the 32 bit version of the flash player which comes with OpenSuSE 11.4 and install a 64 bit version of Adobe Flash which is available from  Adobe Labs. They developed Adobe Flash Player "Square" which is a preview release that enables native 64-bit support on Linux, Mac OS, and Windows operating systems.
Before installing flash player "square" you must uninstall the previous version of flash player. To do this, open kick-off menu, go to Computer and click on Install/Remove Software. After the software manager opens, search for "flash" and select to uninstall flash-player and pullin-flash-player.
Now go to http://labs.adobe.com/downloads/flashplayer10_square.html and click on "Download plug-in for 64-bit Linux (TAR.GZ, 4.1 MB)".
Next step is to install the flash player "square":

- go to the location you saved flashplayer10_2_p3_64bit_linux_111710.tar.gz and extract the .tar.gz archive
- copy libflashplayer.so to /usr/lib64/browser-plugins (note that you must do this as root):

sudo cp libflashplayer.so /usr/lib64/browser-plugins

Restart Firefox and open a web page that contains flash animations or a flash player that you know previously didn't work.

Important: Please note that if you install the Flash Player "Square" preview, you will need to keep this version up to date by manually installing updates from the Flash Player "Square" download page on Adobe Labs. You will not receive automatic update notifications for future final releases of Flash Player, and you will need to manually uninstall Flash Player "Square" before installing a final shipping version of Flash Player.
