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.
