Think about implementing some kind of a history log that stores information about the recently blocked pop-ups:
original page URL;
destination page URL;
timestamp;
maybe an option to whitelist either of the websites (original/destination).
Partly this is needed in order to circumvent the problem when the pop-up is blocked as you follow a link to another page. The notification will not be shown on the new page.
