install FF 2.0 RC3 (latest) in Ubuntu or Debian

Since lot of us have to wait for the newer versions to appear in repositories I wanted to include this quick script for Debian based distros which i found somewhere on the net ... (sorry don't remember the site but IT'S NOT MY WORK)

the only changes are RC2 has been replaced by RC3 since it's the latest
