About
In post made on MacRumors, Jazzzny described PowerFox: “PowerFox is not a derivative of TenFourFox. Rather, it is a brand-new browser for PowerPC, built from the same codebase as the 10.6 Intel variant. To refresh your memory, this brings a modern web engine (UXP) with excellent support for the modern internet, with features such as OpenGL acceleration, coloured emoji, modern HTML/CSS/JavaScript support, container tabs, language packs, video codecs (no need for an “enabler”), and much more.”
