To ride the bleeding edge with Firefox, check out this site:
https://www.ubuntu-inside.me/2009/05/daily-firefox-35-36-repository-for.html

Summary of ubuntu-inside page: The released and nightly versions of firefox can be installed side-by-side, although only one can run at a time. The repository has 2 firefox packages: the usual branded Firefox package, called firefox-3.5 or 3.6, and the other is abrowser-3.5 or 3.6 which refers to an unbranded build of firefox. Install either one.

Be warned! This is DAILY mozila repository.

Edit sources.list to add the appropriate repository, depending on your Ubuntu release :

$sudo gedit /etc/apt/sources.list

And add one of them which matches with your Ubuntu you are using :

While binbash at ubuntu-inside.me describes explains how to install public keys using a script here, I was able to get away with:

$ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys EF4186FE247510BE
$ gpg --export --armor EF4186FE247510BE | sudo apt-key add -

Then update your index :

$sudo apt-get update

Install Firefox 3.6 you can install 3.6 or abrowser instead of firefox, that is your choice) :

$sudo apt-get install firefox-3.6 firefox-3.6-gnome-support

To run from command line: firefox-3.6
Or from menu: Applications > Internet > Namoroka Web Browser.
To use as default firefox, create link from firefox-3.6 to firefox
