TenFourFox. Your Power Mac. Elevated.

New technologies at the heart of the system make
your Power Mac more reliable, capable and responsive —
and lay the foundation for future innovations.
TenFourFox FPR also refines the websites and services
you use every day. It’s TenFourFox at its highest level yet.

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.

[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.
