window.open is bypassed message #17

Closed rayman89 closed 7 years ago

rayman89 commented 7 years ago

On the test page http://tools.add0n.com/popup-blocker.html with window.open button pressed method 3, 14 and 16/2 display a message saying that window.open is bypassed and that it should be blocked.

And with mouse event button pressed methods 2/1, 3, 14 and 16/2 displays the same message.

Why is it showing and what does it mean?

There is a button in the test page to overwrite window.open function. You must have clicked it before running the tests. In Firefox, it is possible to overwrite this function and hence you get the alert message which is basically a simple callback to notify you this function is overwritten. Still popup blocker should be effective and prevent the popups.
