ghostery is great - I use it on my mac and have a running window showing me the volumes of senders trying to spam my screen - I block everything - runs great. Im noticing though in a related issue, I block all cookies.....yet when I clear my browser, several site were somehow still tracking me.....has nothing to do with ghostery though....and is more likely the nsa following me since I’m active here LOL
