Is there anything similar for Aurora? – Devyn Collier Johnson Jul 6 '13 at 19:24

For Aurora, just simply paste this into terminal,

sudo add-apt-repository ppa:ubuntu-mozilla-daily/firefox-aurora
sudo apt-get update
sudo apt-get install firefox

NOTE: You’ll notice that this package name is the same as it is in the official repository. This means that you can’t have both installed at the same time. You can ‘pin’ a package to a given source and version, allowing you to install a specific version from a specific source. But, as long as the package names are the same, they can’t be installed concurrently. You’ll have to compile and execute one version from the source if you want to do this.

Sorry, there is no other way to install Aurora other than doing it over the Stable

I will ask the developers of that PPA if they can tweak the package to allow coexistent installs. – Devyn Collier Johnson Jul 6 '13 at 19:48
Sounds good, if you need anymore help, just comment and i'll try to help the best i can. – Nick Jul 6 '13 at 19:55
