Dear Gina...
When I click on a P411 provider page, it opens as a pop-up in a new window.
I can't tell you how many times I've (almost) gotten in trouble when I close my browser and that ad is still lurking behind it.
Would it be possible to have the pages open on a new tab?
...anyone else?

Learn how to use your technology better. This isn't a her problem, it's a your problem. Plenty of options out there to prevent all kinds of pop-ups. That you almost get yourself caught means you're almost an idiot.
That said, you're mixing your terms here. You say you click the provider page and it pops up, then you call it an ad. So are you saying the providers page opens in a new window (which I recall being the case) or are there pop-up ad(vertisements) which I've never seen p411 have? The former is probably the better "browsing a menu" design a service like that can have, the latter is bad design.
