I try to stick to Firefox for most things and wish they would make this even more intuitive for non-developers. It’d be great if my friends and family could easily toggle between profiles but I don’t want to teach them to type

about:profiles

in the address bar to find those.

Multi-Account Containers is the extension you're looking for. It provides the UI to the feature and it works very well.

Multi-Account Containers is not a frontend for multiple Firefox Profiles. It's a new and separate feature.
