I support a fleet of three classic iMacs, so I was delighted to update to Clasilla 9.2:
Classilla is a free, open source browser for Mac OS 9*
Classilla is bringing back web browser support to your classic Macintosh — built on WaMCom, a port of Mozilla to classic Macintosh systems, using the same technology underpinning the popular Firefox browser. It’s completely free and it’s open source, and it’s standards-compliant. Use it without cost or restriction; or, if you’ve got the skills, hack it and make it your own. Classilla brings your wonderful old Power Macintoshes back to life and back online.
So, big props to Classilla, the Mozilla Foundation, and all others who are working on this wonderful “pre-alpha” project. Thanks!
