Mozilla has a anti-popup feature that is experimental currently but it works flawlessly (for me so far). All you hafta do is add a line of text in a config file and its done.
There is also a program called Pow! that is okay, not nearly as cool as Mozilla's. What Pow! does is matches window titles to a database that you make over time of windows you do not want to pop-up. Naturally, the page has to load before it can close it automatically.
Try mozilla
www.mozilla.org, it owns all other browsers anyway.
oh, and you're off topic, as you can see.
