Wait; what's the point of them if they're not meant to be used against the same site?!

  They are. My guess is that person is doing something wrong.

    The feature is incredibly buggy. I wrote a sibling comment that details some of the glitchiness. It's dangerous to use a system that can't keep sessions independent. There are bugs that may cause you to inadvertently take action in the wrong account. I nearly botched one of our own accounts.

  To isolate the cookies and JavaScript of a domain from other domains. For example, Facebook is notorious for reading third-party site cookies and vice-versa. A collection of associations (X Facebook user visited Y sites) is then sold as a portfolio for targeted advertising. I agree this isn't the feature that provides the most utility; it's simply the one that was originally at the front of the devs' minds.

  isolation of cookies and other data between websites. although now I think firefox does that per tab anyway&site combo nowadays anyway. I mainly use it for multiple reddit accounts and gmail accounts. also good when combined with cookie auto delete for test purpose between testing site changes "freshly".

  I use mine for organization (all banking sites are separate from shopping websites) and to cordon off toxic sites like Facebook.
