This is our advanced test. Your popup blocker should be able to pass every check on this page. If you have not taken our standard popup test yet, start there; it covers the popups you meet every day and gives your blocker a score from 1 to 100.
Nothing here repeats the standard test. That one scores the everyday popups, one window at a time. These three checks probe different ground: a burst of windows from a single click, a popup born inside another popup, and a popup that never uses a link at all. Use the test panel above and follow the prompts. Like the standard test, any window that opens will close itself.
What the Advanced Pop-Up Test Checks
Popup burst: One click, five popups. Your click gives the browser permission for one new window at most, and a good blocker holds that line. Two or more getting through on a single click is a fail.
A popup opening another popup: You click, a window opens, and that window immediately tries to spawn a window of its own. Nobody clicked anything inside it, so the second one should die. Chained popups were the engine behind the old popup storms that buried your desktop in ads.
Form posting to a new tab: Popups do not only come from links. A page can submit an invisible form into a new tab with no click behind it. It is the classic popup ambush in a different coat, and your blocker should treat it that way.
What Happened to the Old Advanced Tests
Earlier versions of this page tested popups fired while a page loads or unloads. Browsers themselves killed those tricks; a modern browser refuses to open a window during page close no matter what the page wants. That war is won, so those checks are retired. The checks above cover the tactics still in use.
