    I feel like the Site Isolation and Total Cookie Protection features eliminated one of the major use-cases for Multi-Account Containers, and that might be why it isn’t getting enough attention.

      I don’t think they’re the same thing. Site isolation prevents Site A to which I’m logged in to know that I’m visiting site B. Multi-container prevents Site A to which I’m logged in to know that I’m visiting same Site A in another tab without being logged in or with a different login. They’re not the same. Typical use case is being logged into work Gmail and personal Gmail.

        And combined with deleting cookies automatically in certain containers, you can have private tabs.

          The best parts of Multi Account Containers are truly streamlined with third party extensions.

          Temporary Containers and Container Bookmarks elevate the experience to a new level.

          I really wish that Firefox could embrace some of this functionality as native, or make it easier for these developers to integrate their extensions into the Firefox ecosystem.
