But modern tracking methods go far beyond whether not you’re actually logged into some site, I’m not sure how this is much of an improvement, your IP remains the same, your browser fingerprint is probably similar enough, if not identical, for them to track you regardless of whether you’re logged in. You only have to be logged in once on the machine from one container for all the other sites you visit in other containers to track you on any site that has a presence or tracking code associated with the one that you’ve logged into somewhere else.
