ubuntuzilla.py -a remove -p firefox
ubuntuzilla.py -a remove -p thunderbird
ubuntuzilla.py -a remove -p seamonkey

2. It is recommended, that you back up your Firefox user profile (located by default in /home/USERNAME/.mozilla/)

3. Add the GPG Key

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C1289A29

4. Add repository for Ubuntuzilla Ubuntu Juanty (9.04), Ubuntu Karmic (9.10) and later

echo -e "\ndeb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main" | sudo tee -a /etc/apt/sources.list > /dev/null

Ubuntu Interpid (8.10), Ubuntu Hardy (8.04) and Earlier

echo -e "\ndeb http://switch.dl.sourceforge.net/project/ubuntuzilla/mozilla/apt all main" | sudo tee -a /etc/apt/sources.list > /dev/null

5. Update repository database

sudo apt-get install firefox-mozilla-build
