firefox has both profiles (for actual different users) and containers for isolating stuff (i.e. a sub-profile) for a single user.

The containers have a great UI/UX. I'm looking at the profile stuff now (after having not in years) and it seems counterintuitive and clunky

Anyway, "forced" is a strong word when you simply mean "prefer". The firefox dev tools are in the same league as the chrome ones, imo.
