I have 10.3 so will upgrade to 10.4 before trying to upload Firefox 3.6. Thanks. Bill

I am running 10.4 and still have this problem. I've downloaded the image from Mozilla twice with the no luck. I've repaired permissions per the advice of the interwebs. Anyone have another suggestion? I really need a copy of Firefox on my G3 Clamshell. Thanks!
