Highlights:
Keeps ad-serving server like Gator under close control
Lowlights:
Has a rather rudimentary user interface. User is only able to open a link in a new window when holding down the CTRL key, or when the 'Allow manual popups' option has been checked.
BotSpot says:
PopUp Dummy gets very high marks for its ad-crushing capabilities - it swallowed up Gator ads with no problem, and made short work of Web-based pop up and Flash ads. It is a shame that the default option does not allow you to directly open links in a new browser window - something that could put off novice users. But a quick dip into the simple configuration panel, and PopUp Dummy finds the right balance between killing ads and letting you surf normally again.
