You could use different Firefox profiles for this...

  I've tried a lot of things. Every option I'm aware of sucks. Even using multiple profiles (which would mostly break the reasons to want to use the same browser) is not really supported (lots of issues with window switching on both Linux and macOS).

  But the icon in the task bar would always be the Firefox one. PWAs solve all the problems here.
