The exact opposite is true.
Google's market share came, first and foremost, from having the best product in each space it dominates: search, browser, email.
The people primarily concerned about "reputation" are a vocal minority. That doesn't mean they're wrong -- but when we're talking about the browser choice of millions of people it's definitely wrong to suppose that reputation is the key factor.
But also based on everyone using google.com for searching and google prompts you to download Chrome when you go there.
I don’t see a way back for Firefox now. To gain market share they’d have to be better than chrome and at best they’re as good - and the more sites build specifically for Chrome, the worse the position Firefox is in.
As small company, I can target Chrome and Safari and cover the vast majority of my potential users. Adding QA and Dev for Firefox just gets harder and harder.
Sites that literally do not load in Firefox? Which ones? I'm genuinely curious here, since I've never hit such a site.

Edit to add that I prefer Firefox in general for philosophical and practical reasons: I'm used to the dev tools and have a hard time navigating the Chrome/Safari alternatives, not to mention Edge/Explorer.
But, to be fair, I also had the opposite issue with some other AWS services where it was working in Firefox but not on Chrome
I use Firefox for almost every site and am I Firefox fan, but you can’t pretend it works flawlessly for ever one.
