[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 the new hot Mozilla 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. 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. Heck, Lion won't even run any PowerPC software anymore. (And 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. They may not be as fast, but 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 modern Firefox'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 today's Firefox 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 512MB 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); see FAQ for info.

[Does someone have a key to your lock?]

Built tough. Built secure. Because your security is your responsibility.

No one at Apple is maintaining Tiger or Leopard anymore. The Genius Bar has told you to stop embarrassing them by bringing your TiBook in for service. The neighbour's kid thinks a PowerPC is a Core i7 with an extra power supply. And you might think that since the world's moved on, they're not going to bother breaking into your old Mac. Well, think again. Even if the latest malware plaguing Intel Macs and Windows PCs won't run on your Power Mac, your security online could still be jeopardized by out-of-date browser software. Your connection to your bank might be easier to snoop than you think. You might be trusting servers you shouldn't trust anymore. Someone might find a way to sneak cookies out of your browser and impersonate you.

As modern life moves even more online, and fewer and fewer browsers for Power Macs are maintained, make sure your browser is as up-to-date as possible. TenFourFox is built on time-tested Mozilla security and encryption -- the same security software used by both Firefox and Google Chrome -- and receives all the security updates Firefox does. No, it's not an iron-clad guarantee you'll be safe: your security is your responsibility. But it's better than you'll get anywhere else. And we trust it enough to use it ourselves.

[Kicking butt and taking names, in JSON!]

The fastest JavaScript on Power Macs.

TenFourFox was the first (and so far the only) browser to bring you accelerated JavaScript on Power Macs. Not just an interpreter, our original tracing just-in-time "JIT" compiler turned JavaScript into PowerPC machine code, making it faster than Safari 5 and over twice as fast as Firefox 3.6, as proven on both the SunSpider and Dromaeo industry-standard JavaScript benchmarks. But we weren't satisfied with that. TenFourFox 10 introduced our method compiler, trouncing even the fastest interpreter by over three times using Mozilla's JaegerMonkey and type inference technologies, and TenFourFox 17 makes it even faster. Not only have we tuned our JIT specially for your processor (even the G5), but our JIT also works on Leopard and Tiger even on the lowliest G3, allowing any Power Mac to pound through today's JavaScript-intensive web applications faster than any other PPC browser and letting you do more than you ever thought before, in less time. Wow, that was fast!

Testing done on 10.5.8 for Safari 5. Result is best of two individual runs. Performance may vary with energy saver settings and available memory. Dromaeo includes both SunSpider and Google V8 tests in its final score. 7450 build used for TenFourFox. Stock builds used for other browsers.
[AltiVec, kids!]

AltiVec™ acceleration, from server to screen.

Remember how AltiVec was going to change the world? Well, it did, because everyone else did it too and now vector and SIMD extensions are in every new Intel CPU and every new browser. But no one brought those new algorithms back to the PowerPC browser world ... until now. In TenFourFox 4, we brought you pixel compositing and WebM video accelerated by AltiVec. In TenFourFox 5, we brought you scaling and colour conversion powered by AltiVec. In TenFourFox 6, we even accelerated HTML itself, and in TenFourFox 8, we not only made that faster but added accelerated JPEG decoding too. Every step of the content chain is faster already, and will get faster in the future. It's the power your G4 and G5 Power Macs always had that TenFourFox finally unlocks. (Don't worry, G3 owners, you can still enjoy all the other benefits of TenFourFox.)
