See Firefox Mac OS X 10.9, 10.10 and 10.11 users move to Extended Support Release. The most current Firefox version you can install is Firefox 78.15.0 ESR, which is no longer being updated.

Download link (English - US): https://archive.mozilla.org/pub/firefox/releases/78.15.0esr/mac/en-US/Firefox%2078.15.0esr.dmg

For other languages, go to https://archive.mozilla.org/pub/firefox/releases/78.15.0esr/mac/
