IMO the vast majority of users cannot make the difference between Chrome and Firefox. They just use whatever they are used to and like it because they are used to it. Over the years, I have converted people to Firefox, Chrome, Brave, Safari. The only common denominator is that they all strongly prefer the one they use now.
