Good addon, Rated 5 out of 5 stars
It's like the blocksite extension, only better and it actually works at removing the blocked sites newly opened tab aswel..
Question .. I disabled the notification alert bar on new popups.. now how do I re-enable it? which about:config entries? "Show visual noticifiicaiton about blocked pop-ups" is ticked on.. yet the bar no longer shows when I know its blocked a popup.
