I cannot install firefox 4 on a G5 iMac, 1.5gb ram OS X 10.5.8

more options

hi, I have tried to install 2 separate versions (4.0 and 4.1/01) of FF4 on this iMac, both won't work with it. What is the minimum system requirements for a Mac to run FF4? writing this from Safari, but about to install FF3.6, which I know works.
