Firefox is not the better browser in anything but privacy. Maybe it could win in customisability, but that’s something only a few percent of users care about.

It has longer load times and sometimes breaks sites entirely while using about the same resources. Yes, the reason for that is that website creators don’t deliberately support it, but the normal user only cares about functionality.

I still use it and recommend it to anyone that asks, but saying that it’s the better browser is just delusional.
