I could not find a Firefox older than 2.0 for my Puppy 4.3.1. However, many websites linked from some posts here are broken or won't work with Seamonkey.
However, I found out that Firefox 3.0.10 is in the Puppy 5 repo. And it works fine with Puppy 4! (I am using Quickset Puppy (based off Puppy 4.3.1 Japanese Edition)...link in signature.
I imagine the results will be the same for many Puppy 4s.
