USE: Test if your web browser is blocking popups on the current page. Force your browser to ask for your popup preferences on the current page.
When the app runs it will attempt to open a test popup window before any prompt is shown. By default, most web browsers will block the first attempt to open a new popup window, because that open action is not directly linked to a user action. If you then click the "OK" button, a popup will often open, because the open action is directly linked to a user click action. The exact results will depend on your browser settings.
