What Are the Disadvantages of Using a Pop-Up Blocker?

The main disadvantage of an aggressive pop-up blocker is that it can interfere with payment gateways (such as PayPal or bank portals) or legitimate PDF downloads by blocking the windows needed to finish the flow.

AdBlock Network handles this drawback elegantly. If a legitimate portal breaks, you can pause the blocker on that domain with one click. For all other sites, the extension makes asynchronous read-only requests to multiple independent endpoints to refresh the firewall, keeping the Address layer active.
