To my understanding: the built-in "Junk" container auto-clears history, as well as "In Private" boundaries apply per usual for any container you open "In Private". Containers that I truly need to regularly clear history on, divorced from the rest of my Profile go into their own Firefox Profile. MAC is on top of/in addition to Firefox Profiles.
Multi-Account Container nicely reduces the need to juggle different Firefox Profiles, but it doesn't eliminate it. (I certainly still use a mixture of both for a myriad of reasons.)
the opposite is true, too, since "Clear History" in Chrome Profiles behaves correctly and (AFAIK) is scoped just to that Profile unlike our container friend: https://github.com/mozilla/multi-account-containers/issues/3...
I still use them because combined with https://addons.mozilla.org/en-US/firefox/addon/open-url-in-c... ( https://github.com/honsiorovskyi/open-url-in-container ) is a game changer for my workflow but it does make me sad that issue has been open for so long
