Overall I am pretty happy with Firefox these days although the design of the tabs could be better - it is sometimes difficult to see which one is open depending on the theme/color scheme that you are using. Not sure if that can be adjusted in about:config, etc?
103 seems a bit faster than 102 for me as well.
I like that they are adding security features lately:
"Your information now has increased protection from online tracking via Total Cookie Protection enabled by default. All third-party cookies are now isolated into partitioned storage.
Removed a configuration option to allow SHA-1 signatures in certificates: SHA-1 signatures in certificates—long since determined to no longer be secure enough—are now not supported."
So, I'd try it out and see if you can indeed can Chrome. You can always keep it around as backup I suppose.
When customers ask which browser I would recommend, I don't provide much guidance except "not Edge", because of MS's strategies to railroad users into sticking with MS's preferences wrt search engine choice and home page for example.
Firefox is more customisable to the way I like a browser to look and work, and that's about it. I briefly switched to Chrome in the era when Chrome's multithreading support was way in front in Firefox's, but those days are over. I switched back when I felt that FF's multithreading support was ready.
IMO Firefox's greatest issue is when the devs get into deckchair-rearranging mode.
