Last Compatible Versions of Firefox

[GogoChipi]

What are the last compatible versions of Firefox for the following OS X versions? I don’t care about the “last supported” versions, or update capabilities, I only care about compatibilities, if it works or not.

10.10 Yosemite
10.11 El Capitan
10.12 Sierra
10.13 H. Sierra

And the question is for all these base OS X versions, not any updated version of these. I’m about to install some OS X into a new SSD tomorrow just not sure which one yet. The older the OS X, the better for me.

Most of us run the latest version of software, so you are not going to get specific info on this from us. Do your own research.

Hello again.

I just copy/pasted "What are the last compatible versions of Firefox for the following OS X versions" into Google and surprisingly, it came up with this:

What are the last compatible versions of Firefox for the following OS X versions - Google Search

www.google.com

Some useful stuff there. Of course, you could modify the Search Criteria by substituting each OS on your list in place of "the following OS X versions".

Hello again.... Ian

yes thank you I found some info on Mozilla.org that says the latest Firefox 91 version system requirements go back to Sierra 10.12 so that gives me half my list, trying to find the last compatible for El Capitan now.

trying to find the last compatible for El Capitan now.

FWIW: my most recent updated version of Firefox used with my Mavericks 10.9 5 macOS and that on my wife's El Capitan 10.11.x is version 78.13.0esr (64-bit). The update was just recently available and installed and it seems to still work fine on both our iMacs.
