FoxTester extension provides a great and convenient way to install and test Firefox 4.0 beta in Ubuntu Lucid Lynx, it also works on other *nix distributions as well like Fedora 13  Goddard  (you might need to disable SELinux as described here) and OpenSUSE. The installation and usage involves the following steps.

Step 1: Download and install the FoxTester extension from the link given as you would install any other Firefox extension. Restart Firefox to complete installation.

Step 2: Now access the FoxTester Preferences, either via the right click context menu or via Tools> Add-ons > Extensions > Preferences.

Now you should see a preferences box like this

The watched folder would be empty if you are accessing these preferences settings for the first time. Choose the folder where you have downloaded or are going to download the beta file. You can download it from here.

Step 3: Now from the context menu that you get by right clicking anywhere inside the Firefox window, choose the option to install the download Firefox beta.

The FoxTester Alert would tell you that the beta was installed. Now use the context menu again to launch the newly installed Firefox beta. This procedure is perfectly safe and won’t alter any of the settings for the original Firefox installation. Enjoy Firefox Beta 4 on Ubuntu.

By the way don’t get disappointed, the upcoming Firefox interface should be soon available on *nix to.
