Firefox 5 on ubuntu 10.04 LTS

For people who are using ubuntu 10.04, the default version of Firefox is 3.6. (Seriously?) It's suggested that you update to the latest stable version of ubuntu.

To install the latest "stable" version of ubuntu, add the following ppa repository:

sudo add-apt-repository ppa:mozillateam/firefox-stable

This is nothing more than add a mozillateam-firefox-stable-lucid.list to "/etc/apt/sources.list.d".

Than, do "sudo apt-get update && sudo apt-get upgrade" and you are done.
