This is the download repository for TenFourFox 24 and beyond, the Firefox port for Power Macintosh computers running 10.4 and 10.5. TenFourFox is not an official Mozilla product and is not a Mozilla-maintained build of Firefox. PowerPC forever!

Our SF repo is only for hosting our current and future downloads at this time (thanks, SourceForge!); Google Code still hosts our wiki, FAQ and issue tracker, as well as all historical downloads prior to 24.1: http://tenfourfox.googlecode.com/

Do not open trouble tickets here -- they will be DELETED. If you are an end-user requiring support, please visit our Tenderapp support ticketing site: http://tenfourfox.tenderapp.com/
