Are you looking for a web browser for Mac OS 8.6-9.2.2 (and compatible with 10.1.5-10.3.9)? Try our sister project, Classilla.
[TenFourFox. The world's most advanced web browser. Finely tuned for PowerPC.]
[Sad Power Mac! But we will make those blue electrons brown again!]

Mozilla left you. Apple left you. But we didn't.

We love Mozilla software. We love Firefox and Camino. We think Mozilla 2 has every possibility of kicking WebKit back into the margins where it belongs. But we were horrified when Mozilla delivered the one-two punch of dropping both support for Tiger and our beloved Power Macs from Firefox 4. A quad 2.5GHz G5 isn't worth using to surf the web? Really? And you guys still support Windows XP?

And, of course, Apple's been giving us Power Mac users the proverbial middle digit since 2006. Remember: think different. That's why your MacBook has the same hoary old architecture in ye old generic Wintel box, and if you want to use your perfectly good OS 9 software, you're using Tiger or bust. Don't get us started on Sheepshaver. It's a great hack, but Classic beats it cold.

[Because we know how you love a modern web browser!] But if there's one thing we've learned from our years of using Macs, it's that they outlast anything else out there. Why shouldn't an iBook be able to look at embarrassing pictures on Facebook, or Twitter about our lunch break? These are our computers, dang it. We paid good money for them. They still work. There's no technical reason they can't do everything that a MacBook can. So if you want something done, you do it yourself, and we did. The result is TenFourFox.

[Make your processor feel special with processor-special builds.]

Tuned for your operating system and processor.

Why is this TenFourFox and not Firefox? Because even though it uses the Firefox code base, it's not Firefox. It uses code tuned for 10.4 (and compatible with 10.5), adds new PowerPC-specific improvements and restores the glue necessary to get most of Firefox 4's advanced features working on our older computers, offered in separately hand-tuned builds for G3, G4/7400, G4/7450 and G5 processors to get the most from your specific computer.

Nevertheless, it's still almost all the same code as Firefox 4 and has nearly all the same features, including dramatically faster JavaScript, WebM video, compatibility with most Firefox add-ons, and HTML 5 and CSS 3 support. You'll find TenFourFox significantly faster overall than Firefox 3.6, yet it supports so many more new and emerging Web features that your dear old Power Mac will still be able to do what you need online for years to come.

TenFourFox requires a G3 Power Macintosh, Mac OS X v10.4.11 or Mac OS X v10.5.8, 100MB of free disk space and 256MB of RAM. Video playback will be poor on systems slower than 1.25GHz; we recommend a G5. Intel Macintoshes are not supported (and will be mercilessly mocked).

[Kicking butt and taking names, in JSON!]

The fastest JavaScript on Power Macs.

No, that's not chart trickery: TenFourFox's JavaScript interpreter really is faster than Safari 5 and over twice as fast as Firefox 3.6, as proven on both the SunSpider and Dromaeo industry-standard browser JavaScript benchmarks. Thanks to its exclusive native tracing just-in-time compiler, TenFourFox powers through today's JavaScript-intensive web applications faster than any other PowerPC browser on both Tiger and Leopard. We've sent our work back to Mozilla so others can benefit, but with TenFourFox, you can wring the best online performance from your Power Mac now!
Works on G3, G4 and G5. Testing done on 10.5.8 for Safari 5; also works on 10.4. Performance may vary with energy saver settings and available memory. Dromaeo includes both SunSpider and Google V8 tests in its final score. Tested with 10.4Fx b9 7450 build. Firefox 4b9 10.5 7450 build courtesy ElFurbe. Stock builds used for all others.
