In Firefox you can go to about:profiles to easily open new windows using other profiles. I bookmark that page with a keyword for quick access. (Also see about:about for a list of other handy 'about' pages)

A more classic-style profile switcher is available via the '-P' (or '-ProfileManager') command-line switch. If FF is in your $PATH you can run:

  firefox -P

The '-P' switch can also take an argument of a profile name to open it directly.

But yes, it would be nice if at least one of these options were exposed in the UI so it was more discoverable by users.

That's not user friendly or works on all OS (eg: firefox -P). There are also other issues with Firefox profiles. For example, on macOS, using different profiles mess up Firefox's icons on the dock and profiles always open behind the current Firefox window.

There's no way around this. Profile support on Firefox is bad and it's a shame because they've had them for years.

I currently have a firefox -p shortcut, but it's auch worse experience than on chrome and friends.
