XYMer's Home away from Home

Downloaded the new Ghostery. Suddenly a purple button with numbers appeared in the bottom right of most windows. I noticed my menubar Ghostery item had the same number of items. I tried going into Firefox's add-ons to set Ghostery preferences and there are none! You have to go to Ghostery's web site to do this but there isn't any shortcut from add-ons. Maybe direct access to preferences is one of the "advanced" features for which you have to sign up with Ghostery for access?
