I guess it does something, not sure what. Wanted to write review to let know the developer that those floating notifications are way way annoying. It would be good if a user can hide those. When they appear they stay for a longer time than they should. Dragging link to create a shortcut on the desktop is impossible until clicked on those notifications. On some news websites I just disable the add-on before I visit a site, just because of those notifications. They don't mean anything to me nor I care what something something has been blocked. Simple counter on the toolbar icon would be sufficient
