Whoops, the last version of Firefox that runs on your MacOS is the Extended Support Release of Firefox 78. (See: Firefox Mac OS X 10.9, 10.10 and 10.11 users move to Extended Support Release)

You can download that from the archive server at:

http://archive.mozilla.org/pub/firefox/releases/78.15.0esr/mac/en-US/

This folder has the U.S. English version. If you prefer a different language/local, click the .. link above the file name and then click into the one you want.

This article has the steps to install from that .dmg file: How to download and install Firefox on Mac.

Can you get reconnected with your Firefox data?
