What is a "pop-up window"?

Pop-ups are graphical interfaces that suddenly overlay main web content without your consent, disrupting your reading experience with commercial spam or invasive advertisements.

Intelligent perimeter filtering

Not all pop-ups are created equal; some are legitimate, while others are purely promotional. AdBlock Network distinguishes between both. The firewall performs asynchronous, read-only requests to multiple independent endpoints to keep the local filtering database up to date, blocking only those pop-up scripts classified as unwanted via the Address and Advanced layers.
