Firefox does support multiple profiles (not containers but fully isolated profiles) even though it's not exposed in the GUI.
New profiles can be created from Profile Manager (-ProfileManager command line flag) or from about:profiles. A new windows can be started with a different profile either using -P <profile> command line option or from about:profiles.
