TenFourFox. What can your Power Mac do now? Just ask.
Talk about big power. No matter what you're viewing, if you already thought TenFourFox was awesome before, it only gets better. Our best-in-class just-in-time JavaScript compiler is now 20 percent faster. We support more video, audio, font and image formats. Better security. Better privacy. The handy features of Mozilla Firefox® on Intel Macs are now on PowerPC, along with brand-new ways to help you with the things you do every day on your Power Mac.
Ahoy. Your chip's come in.
We're not only compatible with Mac OS X 10.4 and 10.5, but we also build our browser specially optimized for your G3, G4 or G5, add AltiVecTM JPEG, HTML and WebM decoding acceleration for G4 and G5 Macintoshes, and soup up JavaScript performance with IonPower, our best-in-class just-in-time PowerPC script compiler. One of our four versions is just right for your particular Power Mac. And it's always up to date, current and secure.

It's easy to upgrade to tenFOUR Fox.

[Our heroic icon!] So make the jump and keep your Power Mac relevant. Our software is open-source, written by Power Mac users and maintained by Power Mac users, incorporating our custom new PowerPC-only features plus the latest bug fixes, security improvements and all the powerful technology underlying Mozilla Firefox 45 ESR.
