I have cleared all the cookies on my Chrome browser, closed the browser and opened Chrome, navigated to chrome://settings/siteData

I see two new Facebook fr and sb cookies created right away, before visiting Facebook. How did these two cookies get created?

  • "How are they created?" Doesn't appear to be the relevant question. Were they deleted? Do you have browser extensions?

  • Those cookie probably get created due to request to Facebook trackers

Take a look at chrome://settings/content/notifications. If notifications from Facebook are allowed (you find https://www.facebook.com:443 on the Allow list), your browser will connect Facebook in the background to get new notifications. This feature may add some cookies even before you have (wittingly) accessed any pages.
