I don’t spend much time talking about PowerPC based Macs, but here is a web browser for those machines.
As the web site says, the PowerPC is still useful for surfing the web even though Mozilla and Apple no longer develop for it. TenFourFox uses Firefox code base, but fine tunes it for use with MacOS 10.4 and 10.5. It also adds PowerPC specific improvements and makes it possible to get most of Firefox 4′s features working on the older Macs.
It is offered in separate builds for G3, G4/7400, G4/7450 and G5 processors.
The site also lists links for getting web browsers for Mac OS 8.6-9.2.2 from Classilla.
