I actually just gave this another try. First thing I did was see if WebAuthn/U2F support finally works well with Google services, which it now does!
Second thing I did was try to open a private window using the universal macOS shortcut of Cmd+Shift+N. Nothing happened, because Firefox decided to use Cmd+Shift+P unlike all other browsers. No problem, this is a macOS app, I’ll just change the keyboard shortcut in system preferences and I’ll be good to go. Except after doing that, Firefox doesn’t actually respect the remapped shortcut (an issue which has existed for 11 years).
And the baked in color management is not correct for a macOS app, and the right click menus are not Mac-like and don’t respect dark mode.
I thought it was time to make the switch, but the reality is that Firefox is still an even poorer macOS app than Chrome. Fix that and I’ll switch tomorrow, as I really want to ditch Chrome!
Funny, that (also non-standard) keyboard shortcut is not shown in the menu anywhere and thus can't easily be remapped using the standard macOS keyboard preferences. I don't know if my Cmd+Shift+N private window remapping is failing due to the conflict, or if it's Firefox just not knowing about the remapping. But either way, it appears I can't easily remap Firefox's reopen last closed window to Cmd+Shift+T like other macOS browsers use.
