Upgrade Firefox in Ubuntu 10 to Firefox 4

Source: http://ubuntuforums.org/showthread.php?t=1712247

sudo add-apt-repository ppa:mozillateam/firefox-stable
sudo apt-get update
sudo apt-get upgrade or sudo apt-get install firefox ubufox


This repository provides the current mozilla release of firefox, in this case Firefox 4.0.

Bonus: I have seen others complain, and so have I, that the ubuntu language packs get stuck on firefox, are not compatible with 4.0, and are just useless.

To remove these you can remove the langpack directories (using root privileges) from
/usr/lib/firefox-addons/extensions


cd /usr/lib/firefox-addons/extensions
sudo rm -rf *langpack*


Please keep in mind this may be removing more than just the old 3.6 language packs. Please be careful and understand what you are doing before doing this.
