But that ignores the reality. Chrome is implementing new (often privacy harmful) features and because the Chrome market share is high enough websites depend on them. Then the average user has to pick Chrome because "Firefox is broken".

The network effects between website and viewers make the market real and failing to gain a significant market share results in you effectively being cut out and failing to serve the needs of most of your users (unless you can match Chrome's insane pace of development bug-for-bug).

Firefox isn't broken, I literally use it all day long as my browser for work and home usage. Rare occasions I pull out brave, maybe once a month, for something that has an issue, and usually that's not it, it's an extension or something.

I also use it almost exclusively, but sites that don't support it (or more often that just don't test against it and have various broken features) are becoming more common. As the market share shrinks this will become more and more common.
