Classilla is a Modern Web Browser for Classic Mac OS 9
Have an old Mac running OS 9 laying around the closet? Dust it off and bring it into the modern age (of the web at least) with Classilla, an open source port of Mozilla, the same underpinnings of Firefox. It’s a work in progress so don’t expect it to be perfect, but alongside iCab it’s probably the best web browser option available for the classic Mac environment.
Requirements are basic enough to run Classilla: PPC processor, 64MB of RAM either virtual or physical, 50MB of disk space, and Mac OS 8.6 or later, although Mac OS 9.1 is recommended along with a G3 CPU.
For those PPC Macs running older versions of Mac OS X, don’t miss TenFourFox, a modern FireFox port for older pre-intel Macs running 10.4.
