Firefox – How to easily install Mozilla Firefox 3.5 on Ubuntu 9.04

The general update policy of Ubuntu states that application versions will be kept stable during each Ubuntu release other than in exceptional cases. Obviously security patches are still applied when available. This does mean however, with the recent release of Firefox 3.5 that Ubuntu users will have to wait until Ubuntu 9.10 until officially receiving Firefox 3.5.

However, Firefox 3.5 is available in Ubuntu 9.04′s software repository by the package name of ‘firefox-3.5′. The application is named Shiretoko, which does not sound very ‘Firefox’ but is in fact Mozilla’s internal development name for Firefox 3.5. To install the firefox-3.5 package in Ubuntu 9.04, just click here, run the command below or install the package via Synaptic Package Manager (found in System -> Administration).

sudo apt-get install firefox-3.5

Although most users who have installed software via the command line will already realise this, the use of ‘sudo’ to elevate the command to superuser privileges will prompt you for your user password prior to installation.

After installation, you’ll find Firefox 3.5 available under Applications -> Internet -> Shiretoko, or can be executed via the command ‘firefox-3.5′. If you wish to make Firefox 3.5 your default web browse under Ubuntu 9.04, first open Preferred Applications which can be found under System -> Preferences. Under ‘Web Browser’ (on the ‘Internet’ tab) select ‘Custom’ and then enter the command below in the ‘Command’ box.

Now, all new links clicked should open Firefox 3.5 / Shiretoko instead of the previous default.

The inspiration for the article was the many discussions I’ve already had with users regarding how to install the latest version of firefox in Ubuntu 9.04 and also discussions regarding the gerneal update policy of update, i.e. the lack of backporting of popular applications. This is great for stability, can be mean reduced functionality and in the case of the Firefox, performance, in which Firefox 3.5 heavily out performs Firefox 3.0. However, discussion of update policies and release cycles is another topic entirely.

I hope this basic installation guide comes as a help to those users who want Firefox 3.5 in Ubuntu 9.04. Feel free to discuss below, and add comments regarding any alternate installation methods or even your thoughts on whether or not Firefox 3.5 should have been ‘officially’ backported to Ubuntu 9.04.
