Not sure. I've been using separate "Work" and "Personal" profiles at my workplace, and can beautifully have two Firefox sync accounts syncing their own stuff. This limitation of the new Container extension prevents me from using it as I'd never want my personal and work set of extensions, bookmarks, and history to mingle with each other. Big oversight.
