If you can't see anything below this on this page, your browser is too old to understand even Netscape-level HTML. You really need to download Classilla.

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.

*and where possible Mac OS 8.6

Classilla isn't finished

It's worth repeating: Classilla isn't finished. WaMCom's last update was in 2003, and that means over six years of Mozilla patches and updates to catch up on. While Classilla has a lot of critical patches applied (which is why it's being released, even in unfinished form), there are still security, stability and compatibility issues yet to be fixed and many sites still won't work, or worse. You will be using software that is still in evolution. Exciting, right? Yes. And quite possibly unstable. Know what you're getting into. Using Classilla is at your own risk. There are still many bugs!

Remember: the Classilla maintainers and administrators are not responsible for any damage to your computer, data or operating system that Classilla may do. Again, you use Classilla at your OWN RISK. We eat our own dog food, but that doesn't mean it always tastes good.

Classilla is exclusively* for the classic MacOS

While Mozilla is a cross-platform environment, and Classilla is based on its XPFE system, Classilla's highest priority is whether it works on classic Macintosh, and any features that get added all have the same requirement. If it'll work and it'll help, it'll be in Classilla. If Mozilla's code won't work as is and Classilla needs that feature, it'll be rewritten if we can. Classilla isn't designed as an application where MacOS support is an afterthought; it's built to be Mac first and always.

*Well ... maybe for BeOS/PowerPC also. Cameron Kaiser has a real live BeBox/133 and it needs a better browser than NetPositive.

Classilla isn't a typical desktop browser

Classilla focuses on the mobile web and mobile sites, a better fit for our old Macs and old code. It takes a little getting used to, but thanks to today's smartphones, many of the most popular sites have mobile versions that are almost, if not more, functional than their desktop equivalents. And that pays off for us too: simpler pages render faster on old CPUs, use less memory and get more done. Our Macs aren't getting any younger, but with a mobile-oriented browser, they can get faster.

Classilla is a browser with a future

Classilla has two purposes: first and foremost, to get a modern web browser running again on classic Macs. But secondly, it's a seed: not only does it get a process established for building itself, it establishes a template for other free open-source projects to follow. By putting the ability to maintain our own software in our own hands, as users of classic Macs, we ensure that OS 9 will continue to survive. Classilla has a path for maintenance and a means to improve based on a solid foundation. With tools baked right into the browser to even let users dynamically reprogram it, we're putting our code where our mouth is. The future is in your hands, and the future's in your control. This isn't a dead end.

Classilla isn't going to get there without your help

Classilla sure needs users: users appear in server logs, and remind site owners that the whole world isn't using Windows or Internet Explorer. But to continue to advance, Classilla needs contributors -- and you can help out even if you don't know the first thing about developing for OS 9.

Can't code in C or OS 9, but you know a lot about HTML and CSS? Become a distiller and help turn malfunctions into test cases, so that coders can devise specific, targetted fixes. Find out how on the Classilla Wiki.

Know enough C/C++ to be dangerous? Become a coder and help integrate Mozilla patches into Classilla, or even write completely new features. You don't even have to know much about Mac programming to be helpful -- if you know CodeWarrior at all, come help out. Find out how on the Classilla Wiki.

Please make sure that your links and bookmarks point to,
as this site may move to a separate host in the future.
