If y'all'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, yous're out of luck. With the latest major update to their Windows / Mac / Linux browser, Mozilla dropped support for Mac Bone X ten.4 and PowerPC architecture, and while it's pretty obvious that, going forward, older machines and operating systems will exist left behind past software vendors, it's always squeamish 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 Bone, is a fork of Mozilla'south Firefox four.0 that runs on older Macs powered by Tiger and PowerPC CPUs.

Merely 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 suspension? These are our computers, dang information technology. Nosotros paid expert money for them. They however piece of work. There'southward no technical reason they can't do everything that a MacBook can. So if you desire something done, yous exercise it yourself, and we did. The result is TenFourFox.

The browser, bachelor for download here, is a very niche product, simply nosotros're sure it'll manage to build a loyal post-obit over the next months: it uses almost the aforementioned code of the official Firefox four.0, but it'south been entirely rebuilt to add specific improvements for OS X 10.4 every bit information technology "restores the glue necessary to get most of Firefox 4'southward advanced features working on our older computers" with separate builds for G3, G4 and G5 processors. TenFourFox includes most of the features of Firefox 4.0 you know and beloved: extended HTML5 and CSS3 back up, faster Javascript rendering, WebM video, Firefox 4 add-on compatibility. According to the developers, the custom code deployed in TenFourFox granted faster Javascript performances than both Safari five and Firefox 3.6 through SunSpider and Dromaeo benchmarks. Plain the lawmaking has been sent back to Mozilla and then anyone could enjoy the improvements made by the team, and the devs also claims TenFourFox is by far the fastest web browser available on PowerPC Macs running Tiger. As for the requirements:

TenFourFox requires a G3 Power Macintosh, Mac OS Ten v10.four.11 or Mac Bone X v10.v.8, 100MB of free disk infinite and 256MB of RAM. Video playback will be poor on systems slower than 1.25GHz; nosotros recommend a G5. Intel Macintoshes are not supported (and will be mercilessly mocked).
