August 17, 2012: This tutorial is for an outdated version of Safari. Please click here to learn how to enable or disable the pop-up blocker in Safari 5.x and 6.x.
Your Safari pop-up blocker should now be activated. To verify this, click on Safari in your Safari menu, located at the top of the screen. When the drop-down appears, the Block Pop-Up Windows menu item should now have a check mark next to it (see example below).
To confirm that the pop-up blocker is working correctly, visit Popup Test and run one of the several tests available there.
