If you're still rocking a PowerPC Mac with a G3, G4 or G5 processor running OS X Tiger and you're willing to try the new Firefox 4.0, you're out of luck. With the latest major update to their Windows / Mac / Linux browser, Mozilla dropped support for Mac OS X 10.4 and PowerPC architecture, and while it's pretty obvious that, going forward, older machines and operating systems will be left behind by software vendors, it's always nice to find alternatives and hacks that enable users who are "stuck" on these systems to enjoy the recent advancements in technology, although with some compromises. TenFourFox, a new project from the creators of the Classila browser for classic Mac OS, is a fork of Mozilla's Firefox 4.0 that runs on older Macs powered by Tiger and PowerPC CPUs.
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.
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).
