This is an old thread, but for all those using ubuntuzilla, it appears that it is no longer being maintained. I went back to using Ubuntu's releases of Firefox and Thunderbird since it seems that Ubuntu updates them on a regular basis. Here are the instructions to go back IF
you used the ubuntuzilla repository method
To uninstall the packages, uninstall the *-mozilla-build packages, using your favorite package manager. E.g., using apt-get:sudo apt-get remove firefox-mozilla-build
sudo apt-get remove thunderbird-mozilla-build
sudo apt-get remove seamonkey-mozilla-build
If you no longer wish to have the Ubuntuzilla repository in your sources, you can edit it out of your /etc/apt/sources.list. deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
If you used the old ubuntuzilla python script method
, refer to the instructions at:http://sourceforge.net/apps/mediawiki/ubuntuzilla/index.php?title=Ubuntuzilla_Installer_Script
Go to "Removal" towards the bottom of the page.
When you finish these procedures, you will automatically go back to the default Mozilla products.
