I've never had any problems, and Privacy Badger has an easy to use inteface. I'm no expert, but I get the feeling I am notified of Trackers when I click on the Badger Icon, and can deactivate cookies etc I don't want. Also, when I deactivate something that was essential to the working of the Site, Badger can tell me that Deactivating this may cause problems, and I can easily reactivate it or leave the site. Excelent Service for free.
