openSUSE: Installing flash player plugin on any internet browser

Download Flash Player installer in .tar.gz format from this site. Run these commands in the directory where you saved the archive:

~> tar -xvvzf install_flash_player_9_linux.tar.gz
~> cd install_flash_player_9_linux
~> sudo cp libflashplayer.so /usr/lib/browser-plugins

Enter root's password, restart any running internet browser and that's it. Worked for me for Firefox.
