“If you believe that mozilla.org is just a smokescreen, that the organization exists only to swindle you out of your hard work for the benefit of some shambling inhuman beast of a corporation, then don't contribute to it.
Take the source code, and build your own browser based on it. Fork the tree. Do what's right.” — Jamie Zawinski (23-Nov-98)

The Originals

The SeaMonkey Project IS the original Mozilla fork in more ways than one. It has been an inspiration to many for some 20 years as it has charted its own unique course and continues to navigate towards The Future™.

SeaMonkey Internet Application Suite by The SeaMonkey Project
SeaMonkey consists of a web browser, which is a descendant of the Netscape family, an e-mail and news client program, an HTML editor and an IRC client (ChatZilla).

Classical XUL Internet Clients

These are applications that for better or worse stick to an interpretation of Classical Mozilla. Many are no longer active and a few evolved.
