If someone from Mozilla is reading this: I (and I suspect many other people who prefer to strictly segregate their “work” and “personal” data), would very much prefer if you implemented built-in profile switching a-la Chrome. This shouldn’t even be that hard given that FF already supports profiles. This is, and has always been, an obstacle for me to seriously consider Firefox as my only browser.

I know about those, but they are almost the opposite of what I want to have: instead of completely separating the two worlds, they forcibly merge them in the same browser instance (and Sync account).

The UI isn't as pretty, but Firefox does support fully separated profiles. More info at https://support.mozilla.org/en-US/kb/profile-manager-create-...

You can also use command line flags to do the same. For example, you can run `firefox --profile $(mktemp -d) --new-instance` to create a temporary, throwaway profile. (Change --new-instance to --no-remote on Windows).

The about:profiles UI is not very polished, but it does exist.
