Install flash player 10 beta 2
Flash player 10 beta 2 is out and it should perform better on Ubuntu.
Start by removing flash 9.
I just removed the file in /home/.mozilla/plugin
(.mozilla is a hidden file, press “ctrl+h” to view it (kubuntu -> “ctrl + .”))
Then copy/paste this command in a terminal.
tar -zxvf flashplayer10_install_linux_070208.tar.gz
Make sure to close firefox when you run the script.
The flashplayer script will ask you some questions, just press “y” followed by an enter, the second time choose “n”.
That should do it.
