AdBlocker Ultimate works pretty flawlessly at what it is supposed to do. Open Facebook for example ones and it blocks sixty -60 - ads right away. In addition I Iike the new feature where they pretty much always block the annoying pop-ups telling you to turn off adblocker or whitelist pages. Of course I don´t whitelist. If I did I wouldn´t need Adblock in the first place!! Adblocker Ultimate has always been a great program and now it just gets better and better! Highly recomended :)
