I'll kill the thread later. But remember that
Edge and
Brave (my own choice for default browser) both use the
Chrome engine, so the only truly meaningful distinction is between
Chrome and
Firefox.
Safari also uses the
Chrome engine, but with its own
Cupertino Variations™, so that one does sometimes behave differently.
On mobiles, of course, all bets are off. It's still the wild, wild west out there.
