How do I start Firefox 4 from KMenu when I downloaded and installed Firefox4.0.tar.bz2 (only launches from terminal), and 'apt-get' installs Firefox 3.6.15 even though I tried to "--purge" it from Linux?

Question

I downloaded and installed Firefox 4 RC using tar.bz2 so that I could still use Firefox 3.6.15 as per normal, having to start Firefox 4 using the terminal which worked great (except for many videos on different websites). When Firefox 4 was released, I suppose I was in a hurry to get it to work normal from my menu, but it kept saying that 3.6.15 was the latest version (I'll be quite embarrassed if it wasn't available for Linux users - I do love Firefox!). I did something silly, like purge Firefox from my operating system (Kubuntu 10.10) and when I reinstalled it was still 3.6.15 (it wasn't really downloading, but unpacking). Am I in too much of a hurry or is there a fix-it? I can use Firefox 4, but only through the terminal and I suspect it is slower than it should be. I would like only one version now.

First, that cannot be an iBook G4 as that machine cannot run Snow Leopard let alone Mountain Lion.  To run Snow Leopard it has to be an Intel processor, not a G4.  What does it show as the Model Identifier in About This Mac, More Info, System Report, Hardware, Model Identifier?
Second, if you have erased the hard drive there should not be remnants of any prior content.  Even though Disk Warrior is saying nothing is wrong with the hard drive, it sounds as though there are problems.  You may want to consider simply replacing the hard drive so there are no questions about faults.  A good source is OWC, http://www.macsales.com where they also have on-line videos showing how to do the replacement.
Third, you could also try again to restart using the Snow Leopard DVD/CD and use Disk Utility on that install disk to erase again, and do it a couple times, then try to install.  If it continues to refuse, then it sounds as though there is a fault with the hard drive.
