With the new accelerated development (or rather versioning) of Firefox, Firefox 5 beta had been released a few days back. In this post, we will tell you how to install from Mozilla's PPA.
As of now, there are not much visible changes between Firefox 4 and Firefox 5. There are a few improvements under the hood though. In the release note, it is said Firefox 5 has better Linux integration - I am yet to see what they mean.
The PPA contains Firefox 5 for Ubuntu 11.04 and Ubuntu 10.04. Anyway, if you want to install Firefox 5 beta in your system, here is what you have to do.
Note: Firefox 5 beta may break or not function as intended. Install it at your own risk.
Open the Terminal and add the PPA.
$ sudo add-apt-repository ppa:mozillateam/firefox-next
After the PPA has been added, update the software list and install Firefox.
$ suo apt-get update
$ sudo apt-get install firefox
That is it. You should now have Firefox 5 beta installed.
