Facebook and Chrome connections revealed via Little Snitch

I decided to make a video showing how many connections are made after starting Chrome

And connecting to Facebook

When I opened Facebook in Firefox it made a connection to http://cx.atdmt.com which after visiting shows 1x1px GIF image. Wikipedia info about Atdmt https://en.wikipedia.org/wiki/Atdmt contains the following: “ATDMT is a tracking cookie served by Facebook subsidiary Atlas Solutions and used as a third party cookie by several websites.”
Opening FB in Chrome made connection to http://pixel.quantserve.com which after visiting informs that it is “Quantcast Measurement Service”, they provide also a table of most visited sites at https://ak.quantcast.com/top-sites. Quantcast on wikipedia https://en.wikipedia.org/wiki/Quantcast

Be aware of the watchers 😉
