eAnthology's Popup Blocker stops website generated advertising popups, without stopping the popups you want, like "more info" popups and links you click on.
Popup Blocker can sound a chime when it blocks a popup, so that you know when a popup has been stopped. It also keeps a running total of all popups stopped. The trial version is free. Paid users can sign up for levels of service that include eAnthology’s entire computer protection service that comes with unlimited live tech support. The most expensive option is $10 per month, which includes all of this plus kon-X dial up service.
