The myth of the dangerous cookie 

Quit Safari.

In Finder go to Go menu and then Go to Folder.

Copy and paste this ~/Library/Safari/Databases.

Delete the contents of the folder.

Launch Safari again and check if all is ok.

Delete the contents of the folder.

Then go to Safari/History and delete any entries for the related websites.

Test.

EtreCheck, please?

You’re probably going to have to either track the cookies from each site as you browse and see which one adds this, or maybe enable and use an ad-blocker. An app which almost inherently tracks activity.
