Same, I use Firefox 90% of the time and I have no idea what all the complaining is about. My only real issue is that fullscreening videos on macOS sucks (ie, it takes forever).
I certainly don't personally care about declining market share, that's not my problem. Mozilla makes a good product. Chrome has become the default browser thanks to Google's muscle (and also making a good product), and I dunno what grand strategy is supposed to compete with that.

Agree 100%.
In its current state I find Firefox simply _better_ than Chrome - mostly due to how well integrated Multi-Account Containers are. Like you I am puzzled by exactly what is Firefox missing that it is a deal breaker for people. Is it just the occasional hiccup when using a Google/MS service? Some people mention 4K videos not playing properly - that sounds like an acceptable reason. But surely that still isn't a good reason for not being able to have Firefox as one's daily driver.
I have the same suspicion as you, Chrome's marketshare is simply because Google services are so popular and they direct you to Chrome, and that the most popular mobile OS (Android) runs Chrome by default.
