That's unfortunate, but you don't have to use Firefox. I don't understand why some people think more options are bad. You can still use Safari or Chrome.
Firefox is barely alive because of mismanagement and Google’s dirty tactics. If one could give access to Firefox while blocking Chrome that would be ideal.
But then you've stooped to their level.
There are plenty of Chrome based alternatives that are not spyware of you are bothered by that.
Firefox won from IE. it successfully broke the IE monopoly and gained significant market share. Then, years later, chrome entered the stage and conquered both.
Then came Chrome.
Yes, Firefox usage peaked at about 20%: surely not negligible (didn't know anybody myself using it !). As for geographical distribution, I could only find this: https://gs.statcounter.com/browser-market-share#monthly-2009... The data goes back up to 2009, which was quite a peak period for FF...
Sure FF has played an important role in the browsers war, but it hardly broke the monopoly, or at least it did not do it alone (Safari and Opera started to gain a significative share at the same time).

Firefox was growing constantly before Chrome started taking over.
Those people using Firefox weren't a small minority, and they weren't techies only.
You're trying to rewrite history from your small bubble.
