> And I know of no system that allows different simultaneous workspaces with their own IDs, nor browser that allows the same with tabs

I'm probably missing something, but Microsoft makes it reasonably easy to switch from personal account to work account _even with the same email address_ -- in Microsoft Edge in the same profile, in the mobile Outlook & OneDrive apps, and so forth.

Sure it could be better, but the simple workaround is to just create a browser profile (which is pretty easy to do in Chrome and indeed in Edge) per family member, set up distinctive themes for each profile, and so on.

Of course this is also possible with Firefox.

I don’t even want to risk my personal account getting mixed up with my work account. I keep those things absolutely separated.

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.
