too many times they don't block the pop-ups or pop-unders and do block the desired pop-ups, I wish someone with programming abilities far above mine (wouldn't take much) would fix that kind of thing, where the desired content wouldn't be blocked by a simple blocker and all ads would be. Of course as soon as you do that, someone would program a way around it. Or how about a muter or automatic pause--get the content if you wish, but don't set to come on if you don't opt in--for automatic videos that no one, except the site programmer, asked for?
