Manually Update Firefox Mac Os X 10.5 8 To 10.6.8 Somewhere I saw that mac mini 10.6.8 does not support anything after Firefox 17. It is OSX 10.5.x that suported Firefox 16.0 at most as OSX 10.6+ supports. Mac 10.9.5 upgrade. Fast downloads of the latest free software!*** Mozilla Firefox is a fast, light and tidy open source web browser.
