At one point I installed the newest version of Firefox on my MAC (Early 2008) running Catalina. I found it would not run as that release needs a newer MAC OS.

So I went back and installed Version 78. That did not work either. So I tried Firefox 10.0.11esr.dmg, 10.0.9esr.dmg, and even Firefox.45.9.0esr.dmg.

After install, I get the same message.

You can't use this version of the application Firefox with this version of OS. You have 10.11.6, This application requires 10.12 or later.

My theory is that even though I uninstall Firefox, some trigger file gets left behind and I get this error message no matter what version of Firefox I install.

Anybody have any ideas on how I can run an older version of Firefox?

I have hit the Sept 30 Certification issue with this old MAC and I hope Firefox will be a work around. - Thanks Rod

When I was using version 88.x, Firefox had not crashed for years. Then all of a sudden, Firefox would crash several times a day. I looked and Firefox had updated me to ver 89.0. But I let it ride. Then Firefox about a month ago, Firefox stsrted to crash EVERY DAY. Then one day it crashed EIGHT TIMES IN A ROW and I mean when I hit RESTART, IT WOULD CRASH. I tried to revert to rel 88 but Mozilla WILL NOT ALLOW US TO REVERT BACK TO A PREVIOUS VERSION. When you do, the PROFILE gives you TWO OPTIONS: 'EXIT or CREATE A NEW PROFILE.' Certainly you do not want to CREATE A NEW PROFILE as you will LOSE, your history, add-ons, Bookmarks, EVERYTHING and you see a WHITE Firefox screen with nothing. So I choose EXIT and tried to put up with the CRAPPY ver 89. BUT FIREFOX KEPT CRASHING. TODAY IT CRASHED SIX TIMES IN A ROW......When I checked the VERSION, YOU HAD UPGRADED TO VER 91.0b6 (64-bit) AND IT IS NO BETTER.

WHAT IN THE HECK IS GOING ON. I DO NOT WANT TO LEARN CHROME OR EDGE AS I HAVE USED FIREFOX SINCE VERSION 1.0.

DOES ANYONE KNOW HOW TO GO BACK AND KEEP YOUR OLD PROFILE, FLACKY OR NOT AS THAT IS BETTER THAN 'RESTARTING' FIREFOX ALL THE TIME.

MY VERSION 88 NEVER FAILED.
