I use pop up stopper, and its great. Im using an older version, and it is absolute, no explorer window opens, NONE, unless i hold control and let the window open. It looks like the never version works like pow, and you can build a database of allowed windows. Im going to check out pow, but i think people should check out pop up stopper as well.
between this and a cookie manager, i now run clean on the net. I just ran a ads aware program and i was clean as a whistle. Ahahahahah, now all i need is a good proxy and i can roam the internet like a ghost.
