Update theĭisplayError function to handle the error message as you see fit. This solution for popup blocker checking has been tested in FF (v11), So the first one is blocked, and the second one is not. The difference is that Firefox treats a timeout of 2000ms or less are acceptable, but after it – removes the “trust”, assuming that now it’s “outside of the user action”. …And this works in Firefox too: // open after 1 seconds The popup opens in Chrome, but gets blocked in Firefox.

But what is the popup opens in setTimeout? If you remove unwanted programs or reset. On Windows: Click Reset and cleanup Reset settings to their original defaults Reset settings. If the code is directly in an onclick handler, then that’s easy. On Chromebook, Linux and Mac: Click Reset settings Restore settings to their original defaults Reset settings.

So now most browsers try to block popups and protect the user. A bad page could open tons of popup windows with ads. A pop-up is a graphical user interface (GUI) display area, usually a small window, that suddenly appears (pops up) in the foreground of the visual interface.

The initial idea was to show another content without closing the main window.
