Aligning with precedent that modified builds of Firefox source could not use Firefox trademarks without permission, the project was forked and named TenFourFox. This was released to users in separate builds for AltiVec Macs and G3 Macs on November 8, 2010. In response, developer Cameron Kaiser created a test build of Firefox 4 that could run on his Power Mac G5 at the same time as support was being withdrawn from beta 7. Mozilla stopped making PowerPC-compatible universal builds of Firefox 4 with beta 7. In 2010, Mozilla's Mike Beltzner announced that the forthcoming Firefox 4 would not be released for Power Macintosh computers, compatibility with Mac OS X Tiger having already been removed, making Firefox 3.6 the last supported release of Firefox on the older architecture and platform.

The project shares administration with Classilla, a fork of Mozilla Application Suite for Mac OS 9 and Mac OS 8.6. The primary maintainer is Cameron Kaiser. It also includes JavaScriptjust-in-time compilation, custom builds for specific PowerPC processor families, and AltiVec acceleration of key media codecs.

Like Firefox, it includes compatibility with a wide range of addons, Acid2 and Acid3 compliance, and HTML 5 and CSS 3 features.

The project was started after Mozilla announced that it would not release Firefox 4 for PowerPC versions of OS X. It is a port of Mozilla Firefox for PowerPC-based Macintosh computers running Mac OS X to retain compatibility with the older architecture and older versions of the operating system, and to add PowerPC-specific optimizations for improved performance. TenFourFox is a web browser for Power Macintosh computers, based on Mozilla's Geckolayout engine. Mozilla Public License, GNU General Public License, others

Download Old Version of Opera for Mac for Mac OS X 10.4 Tiger (PowerPC). 12.0 is most definitely not compatible with the version of OS X on my MacBook Pro. Whenever I load Firefox it tells me to upgrade to 12.0 for security reasons. I'm running Mac OS X 10.4.11 'Intel,' TenFourFox doesn't help with that. Similar to other optimized build projects such as Pale Moon and Swiftfox, TenFourFox includes specific compiler optimizations to improve its overall performance and issues specific builds tuned for specific processor families.

TenFourFox shares its main feature set with Firefox along with optimizations for the PowerPC platform.
