Install or upgrade Firefox 4 on Ubuntu


Mozilla just released their newest version of Firefox, in this article I'll try to explain how to install (or upgrade) Firefox finest on Ubuntu.

Open a terminal window in Ubuntu (Applications \ Accessories \ Terminal) and copy and paste the following lines:

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

# sudo apt-get update

# sudo apt-get install firefox


Or if you want to upgrade your existing Firefox, close your Firefox and enter:

# sudo apt-get upgrade


When finished, close your terminal window by entering:

# exit


And enjoy your latest greatest :-)
