Download the player in:

http://labs.adobe.com/downloads/flashplayer9.html and download the installer. It comes tarred and gzipped.

Just type tar -xzvf nameofthefile.tar.gz (in your home directory)

where nameofthefile= FP9_plugin_beta_112006

this will create the directory named: flash-player-plugin-9.0.21.78/

Go to /usr/lib/mozilla-firefox/plugins directory and type:

sudo ln -s /home/yourusername/flash-player-plugin-9.0.21.78/libflashplayer.so .

Don’t forget the last dot.

And that’s all!!

Happy surfing with the last Flash Player!!
