>>212588781chrome does some things better:
moving around windows and tabs in chromium is 10 times more fluid
song recognition extensions are dogshit on firefox
and the behaviour where it redirects you to already open tabs if you want to open another one, instead of just opening another, can't be disabled even in config (years old open issue on the mozilla forums, common complaint)
that's the stuff i've noticed from a couple of weeks using it. there's been other minor stuff but found work-arounds so won't complain
