This is where Firefox Containers[1] rules. Just open all these sites in new containers and you can keep them siloed and apart (either not logged in, or under separate accounts). You can have as many as you want and have them auto-assigned based on the website. It's actually an official Firefox project, although it comes as an extension. Though I think it should be a first class feature in the base install.
