The multiple tab function on Internet Explorer 7 and 8 (IE7 and IE8), allows the surfer to have several Web pages open at once without opening multiple, system-slowing, browser windows. Tabs were not available on Internet Explorer 6 (IE6) according to Microsoft. When closing the browser window, a dialog pops up if you have multiple tabs opened. This request to "Close all tabs" becomes a hindrance for some. Stop this pop up query from appearing when you close your Internet Explorer 7 or 8 browser if it is getting in your way.
Change Tabbed Browsing Settings
Open Internet Explorer 7 or 8.
Go to the "Tools" menu and select "Internet options."
Click on the "General" tab and click "Settings" in the "Tabs" area.
Uncheck the box next to "Warn me when closing multiple tabs."
Click "OK," and restart Internet Explorer for your settings to take place.
Use "Close All Tabs" Dialog Box
Open Internet Explorer, and press "Ctrl" and "T" at the same time to open a second tab.
Click on the "X" in the upper left corner to close Internet Explorer.
Click on "Show Options" when the box appears asking "Do you want to close all tabs?"
Check the box next to "Do not show me this dialog again."
Click on the "Close tabs" button to apply the changes.
