You accept these conditions unconditionally by downloading and using Ten Four Fox.We eat our own dog food, but we (and you) do so at (y)our own risk.I use various firefox derivatives on my Trisquel Linux machine so I’ll start to investigate this further.
This evening I was greeted with a message from my trusty firefox installation that OSX 10.7 (Mountain Lion) is no longer supported and as such won’t receive any future updates.
This contradicts the message over on the Firefox support site which states that support will continue to August 2016. This machine is fast (faster than my brother in laws brand new i Mac running OSX El Capitan) in real life even though the hardware is in no way a match.
If you have hit this snag with Firefox you can opt for the Extended support release to buy some time, or start looking for another browser.
Many open source projects are based on Firefox so it might be time to look into those.
It would now appear that Mozilla have brought forward ending support for older versions of OSX and in turn ended support for people wanting to run older hardware.
