I'm using the round menu style as a base and using google ads in a couple sidebar text widgets. Problem is myself and many others use Firefox with adblock plus, so this causes a blank container to be displayed when with most themes nothing is displayed at all. In the image below, you can see what appears just to be a small blank container widget, that is how it shows when it is adblocked.
My question is, how do you make the text widget container not show up at all if it is being adblocked? Obviously it looks fine in Internet Explorer, but looks pretty bad in FF.
