Might I also add that the YouTube thing is also the only chink in the otherwise impervious armor I've had in dealing with the extension (though I'm certain beyond doubt that this is YouTube's fault, not Ad-Block's). Also, Flashblock is a great companion extension that...well...blocks flash files, so those ads go away as well. And of course you can whitelist flash-based ad-free sites (ie, YouTube) so that you're not bothered by the extension.
