I don't trust Mozilla. They continually make changes against the interests of the computer literate, they continually screw with the UI, they continually take control away from the user, they are literally in Google's pocket, and their own attempts at fundraising put the lie to their claims about privacy.

I think Firefox is an important alternative to WebKit/Blink-based browsers.

But as a web developer I semi-regularly butt up against bugs in it that have languished in Bugzilla since like, 2014, with absolutely no progress on them.

I have dealt with two (maybe three?) bugs in Chrome ever and one of them was a pretty clear fuckup they rolled back within days.

From my experience, almost every website doesn't feel as nice in Firefox as it does in Chrome. Ofcourse some of those sites are maintained by Google (YouTube).

Ah right, now i remember. Yes that would be de-googled-chromium then.

User agent spoofing seems like what should be done on the user's end in those cases, if it's not possible to avoid using such sites for whatever reason.

Problems would begin once we'll eventually get Chrome-specific functionality or something that Mozilla won't implement due to a variety of concerns, thus simply breaking sites: https://mozilla.github.io/standards-positions/

Then we'll basically be back in the days of IE, except that this time Google will be the ones with the browser monopoly, if we're not already there somewhat - the majority of folks haven't even heard of Firefox.

My experience is it’s more often proprietary web fronts for corporate microservices than WWW pages

If Firefox won’t work, edge almost always will. I’m really trying not to download chrome again. I forgot chromium is an option. Is that not maintained by Google?

It's mostly some specialized features, like conferencing in Microsoft Teams. Clearly some pieces of web software are optimized only against webkit/chrome. But yeah, not many things outright refuse to work on Firefox these days.
