One of the add-ons I use is "Lightbeam for Firefox" which keeps track of cookies.
Every website you click on links to one website, "Google Analytics".
Google is tracking every link on every browser.
www.google-analytics.com
I run my own DNS, and about 2500 site names resolve to 127.0.0.1
See https://pgl.yoyo.org/adservers/serverlist.php for the list.
They are keeping very busy following me.LOL I’m making them EARN their pay.
Sick.
I use ghostery at home, google analytics gets chomped on almost every link click...
