Seriously, are you using IE or something? Yeesh... You think the ad is browser specific? You really are dumb.
Of course, in this case, you just jumped to an incorrect conclusion. And proving again that you are dumb, the original poster corrected himself/herself within a minute of the original post. You see that one modded +5? Yeah, that one... idiot.
Thanks. Now I remember why I (a few 5-star comments) have quit posting here. Too many dysfunctional assholes here to rip into you.
Oh shit, why do I bother? Anyhow, here's your explanation, anonymous pile of feces: You can't get AB+(or any ad blocker the last time I checked) for IE, so yes, the ad, in this case, IS browser-specific.
Now, you may return to pulling wings off of flies and spying on your sister in the bathroom...
