I've recently gotten very annoyed with popups, so I was wondering if there was a popup blocker out there. Also I recall there was one out there that let you download updates from a site that automatically updated the list of popups to block.
Here is a really good one. It's not the latest version... I don't like the latest one because it doesn't block everything like the older one does. If you want to let a pop-up window open you just have to press ctrl or shift when you click the link.
