Whenever Internet Explorer blocks a popup, if you have kept the default popup blocker settings, it will do three things: first, it will (attempt to) block all non-legitimate windows from opening, display a yellow information bar letting you know that a popup was blocked, and play a sound (Internet Explorer lets you disable the popup blocker sound). Especially if you always have you speakers turned on, and set at an audible volume level, the yellow bar is redundant, since the sound and the "popup blocked" icon in the status bar will let you know that the website tried to open something in a new window, whether it was legitimate or not. In this tutorial, we will show you how to turn off the yellow bar at the top of the screen when Internet Explorer blocks a popup window.
Here is a screenshot of the yellow toolbar Internet Explorer will display when it blocked a popup window: "Pop-up blocked. To see this pop-up or additional options click here..."
This is all you need to do to disable and hide the yellow popup blocker information bar in Internet Explorer 7 and Internet Explorer 8.
Should you decide to restore this functionality later on, no problem: go to the Tools menu (which could look like a gear icon instead of text), choose "Pop-up Blocker", and click on "Pop-up Blocker Settings". And at the bottom of the window that opens, under "Notifications and blocking level", check the "Show Information Bar when a pop-up is blocked" checkbox to re-enable the yellow bar when Internet Explorer successfully blocks popups.
