I give firefox a shot from time to time. I switch all devices to it, and then I use it exclusively all the time.
My most recent attempt failed few days ago, after a bit more than a month with it.
Firefox performance just doesn't feel the same as chrome, from constant small freezes, to using 100% CPU pretty often.
And just overall experience on some platforms - especially macOS doesn't feel native at all. On top of that some websites don't support it that good (not Firefox's fault here - but I don't want to deal with that day to day).
Firefox also seemed snappier on the first few runs, but as the time went on I didn't find it faster or feeling less bloated than chrome as a lot of people like to portray it.
Chrome for me, as an average user, does not have any of these downsides. The closest to a downside for some people you could pin to chrome is that it's owned by google.
At the end of the day, chrome gets the job done, and does it without being in my way, on all the platforms I use, - and that's what I want from a browser, so for now I'm sticking with chrome.
