TenFourFox: Mozilla for Power Macintosh

A fork of Firefox to maintain support for the Power Mac, supporting Mac OS X 10.4 and 10.5, with special features and optimizations for PowerPC processors and AltiVec. This project is not affiliated with nor supported by Mozilla in any way, and is not an official build. PowerPC forever!

This project is specifically for Mac OS X 10.4+. If you're looking for a browser for Mac OS 8.6-10.3, look at our sister project, Classilla.

Our Github project site houses our source code, documentation wiki and issues list. For downloads and archived versions, visit our SourceForge download repository. The most current downloads are always linked on the main TenFourFox home page.

If you are an end-user, or otherwise not an official contributor, do not file issues on Github. Please visit our Tenderapp support site and one of our helpful volunteers will assist. Issues opened by end users may be closed as invalid if they have not been adequately vetted.

The wiki/ branch contains old documentation and release notes from our former Google Code wiki. They are no longer updated or maintained. Take care as links in those documents have probably rotted.
