Have you been to Beck's site? he makes Breitbart look like a pauper. I run "Ghostery" & a Google Blocker, I get over 70 items he is trying to data mine me about. And he has the gall to go on a anti NSA tirade? FWIW, I have tried some of the other top blockers mentioned in this thread, anti-hijacker too. After a while they are doing possibly the same thing and some of these add-on's don't play well with each other and you are then running slower than molasses.
Husband complain sabout Becks site and Yahoo...I keep telling him to stay off them...tried adblock too...we use firefox...aagghh
