This is an old post from a ubuntu forum

http://ubuntuforums.org/archive/index.php/t-947694.html

sudo echo "activate sudo"

echo "deb http://ppa.launchpad.net/fta/ubuntu hardy main
deb-src http://ppa.launchpad.net/fta/ubuntu hardy main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install firefox-3.1

If you don't want to move you icons around and use firefox-3.1b1 as your main browser

sudo dpkg-divert --divert /usr/bin/firefox.ubuntu --rename /usr/bin/firefox
sudo ln -s /usr/bin/firefox-3.1 /usr/bin/firefox



If you want to undo that change
sudo rm /usr/bin/firefox
sudo dpkg-divert --rename --remove /usr/bin/firefox
