G4 7450 optimized verision of firefox 1.07?


Does anyone know where I can find a version of Firefox version 1.07 that is optimized for the G4 7450 processor?

I see a few websites hosting nightly builds of firefox, but that is the beta version of firefox 1.5. I'm not too thrilled about using beta software.
I would like to find a true release version of firefox 1.07 that has been optimized for my processor.
I was using a version way back, maybe 1.01 and it was absolutely amazing! Never seen my Powerbook load pages that fast.
