TenFourFox: A fork of Mozilla Firefox ESR 38 for the Power Macintosh and Mac OS X Tiger PowerPC

Technology, that's what. The highest performance JavaScript ever on a Power Mac. The power of HTML5, powered by Mozilla Firefox, the most trusted name in browsers. The ability to get the content you want with Reader Mode. The choice to remake the browser your own way with a modern, customizeable interface. We took Firefox, made it work with Tiger and Leopard, and refined it piece by piece so that it all soars on even the lowliest G3. Now your Power Mac not only can access all the modern websites and services you enjoy but also harness all the power and compatibility you need to do it. It's a big jump from every previous version, and a revolution from what you've been using. And it's here.

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 AltiVec^TM 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.

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 38 ESR.
