Install Firefox 3 parallel to Iceweasel.

[yamal]

This script looks if the insecure Firefox firefox=2.0.0.11-1mepis1 is installed, and if found replaces it with the latest Iceweasel 2.
After that it will give you the option to install Mozilla's Firefox 3 parallel to Iceweasel in opt.
It will give you a language choice and then downloads that package from the Mozilla server and installs it.
At the end it makes a desktop file, so that an entry appears in the K-menu as an icon that you can drag on to the kicker.

Edit: removed newbie warning, since this is essentially a simple script.
