> It's just hidden behind a clunky UX.

That's part of the "problem" with Firefox's support of profiles. It feels more like an afterthought and less like a primary use case the product wants to surface. To approximate the functionality Chrome has, I had to bookmark "about:profiles" and make it my home page.

Chrome also added this nifty feature that lets you open links as a Profile, making it easy to switch.

These may seem like small issues, but the end up mattering.
