By default, Mozilla Firefox doesn't block any pop-ups that are opened through mouse clicks or other user events. However, some sites use those popups for advertising and even Adblock doesn't block them by default.
To block an unwanted pop-up window with this extension just add the window's url to Adblock's filter list and any popup window matching that pattern is prevented from being opened. You can also block all pop-ups from specified domain by adding it to addon's blacklist.
Note that Adblock Plus is required for this addon to work. If you get a message saying additional items required it means that you don't have Adblock Plus installed.
