AquaFox is a continuation of the TenFourFox (and then InterWebPPC) project, which integrates the occasional updates Dr Kaiser still releases, and has builds for each PPC revision (G3, G4, G4e, G5) which is really nice.<p>Sadly these machines simply don't have the horsepower to browse the web well these days, but for those times you want to look something up or download a file without moving to another computer it's a really convenient resource.
