Multi-container will break any SSO experience that depends on cookies, where the sso domain (abc.sso.com) is not pinned to a container, and the destination domain (abc.com) is pinned to a container, due to the correct behavior of not allowing cookies to be copied into the container when the SSO chain of requests traverses from abc.sso.com -> abc.com.

This plus the inherent back button hijacking when you click a link that throws you into another container (which works by opening the link in the new container tab, changing to it, and closing the original tab), led me to just stick with facebook containers and sacrifice the privacy offered by multi account containers for some convenience.
