FF also has multiple profiles feature. But nothing matches Containers. Containers are different. Containers keep only the identity data (sesssion, cookies etc.) separate. All other data is shared. Profiles are painful. History, Password Manager, Bookmarks all are accessible and shared across FF containers. This makes it really useful.
