While not neccesarily a popup stopper but more an ad blanker

It is very effective

Update your hosts file using this comprehensive list

http://www.accs-net.com/hosts/get_hosts.html

And then install Edexter <- link on site above

The hosts file blocks all servers mentioned while edexter replaces the "file not found" error you cause with a nice blank image or one of your choice.

Essentially by adding sites to your hosts file you tell the computer to check itself for the site and when it doesnt find it it errors.

Post if you have any questions

Thanks
