Why Do I Still Get Pop-Ups Even When They Are Blocked?

It is frustrating to enable Chrome's blocker and still see pop-up tabs opening with spam or betting ads. This happens because modern advertisers write complex scripts that bypass default browser filter checks.

Background Logical Interception of Window Triggers

The extension makes asynchronous read-only requests to multiple independent endpoints to refresh the firewall, running Advanced rules that intercept the logical functions responsible for opening pop-ups.
