Install the Latest Versions of Firefox and Thunderbird Using Ubuntuzilla
If you are running Ubuntu or any of its derivatives and you want to use the latest and greatest versions of the Firefox browser and the Thunderbird mail client, Ubuntuzilla has the solution for you. The project maintains a software repository containing the latest packages of Firefox, Thunderbird, and Seamonkey. And you install any of these packages on your system in three supremely easy steps. First, you have to add the Ubuntuzilla repository to your sources list. You can do this by adding the following line to the list of third-party repositories in the Synaptic package manager:
deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
Alternatively, you can add the repository by running the following command in the terminal:
echo -e "\ndeb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main" | sudo tee -a /etc/apt/sources.list > /dev/null
Next, add the package signing key using the following command:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C1289A29
Update then the package database using the sudo apt-get update command, and you are done. To get the latest version of Firefox, install the firefox-mozilla-build package. You can do this either using Synaptic or running the command below:
sudo apt-get install firefox-mozilla-build
The Firefox version installed from the Ubuntuzilla repositories appears in the Applications -> Internet menu as Mozilla Build of Firefox. In a similar manner, you can install Thunderbird (the thunderbird-mozilla-build package) and Seamonkey (the seamonkey-mozilla-build package).
