Installing new firefox on Acer Aspire One linpus lite
my old firefox is obsolete. I've downloaded 3.6, successfully as far as I can see, but it's just sitting there on the hard drive as a file, it doesn't start up, I just get the same old version 2 which came with the machine and it's dead in the water really.
Can anyone tell me what to do next to get 3.6 to run please?
I can follow instructions but I don't actually know anything.
