Microsoft Internet Explorer 8 Redisplay Warning When Closing Multiple Tabs

Force Internet Explorer 8 to warn you when closing the browser if multiple tabs are open in case it fails to do so.
By default, Internet Explorer 8 should warn you when you attempt to close the browser and multiple tabs are open. This helps prevent an "oops" if you meant to only close Bing while Twitter, Facebook, CNN, ESPN, and MalekTips are also open, for example.
If you tire of these warnings, the dialog box also contains an area you can check to "Always close all tabs". However, what if you later change your mind or accidentally check this box and didn't mean to? You can configure Internet Explorer 8 to show these warnings again later if desired:
1 . Access the Internet Options dialog box. If the menu bar is visible, you can select "Tools" - "Internet Options". If the Command Bar is visible, click the "Tools" button and select "Internet Options". If neither are available, try typing Alt + T then O.

3. The "Tabbed Browsing Settings" dialog box appears. Check "Warn me when closing multiple tabs".
