I use Temporary Containers all day. Love this addon. This is fantastic not only for privacy/security for everyday use but also great for testing sites while doing development. It becomes really easy to be logged into all the different types of users in a website at the same time and see the interaction.
Agreed. I have mine in automatic mode. My default browsing experience is that most pages have never seen my computer before (at least as far as cookies go), and don't get to set anything that will stick around, unless I manually add them to a named container.
