I&#x27;m not sure incognito browsing actually helps much.<p>User tracking isn&#x27;t a 100% accurate science, and your browser name, browser version, operating system, OS version, IP address, screen resolution, etc. are still getting sent along and they don&#x27;t change by going incognito.  It&#x27;s no big deal for Facebook to just assume it&#x27;s still you if the only thing that&#x27;s changed is that you&#x27;re no longer sending the same session cookie.
