I've been using this add-on but I just realized I seem to have Close buttons ('x' in a circle) even when it's disabled and even after I uninstalled it. Either one of the recent FF updates added this or one of my Stylish updates snuck it in...(just to be clear I never had a problem with it it just seems "otiose" now.) :-)
