IE provides the ability to install add-ons to extend the functionality of the browser. Add-ons can be used to improve usability and security, or simply to provide entertainment. Add-ons are created not only by Microsoft but by third parties as well.

Add-ons can be installed by clicking Find More Add-ons and selecting the desired add-on from the list displayed on the Add-ons for Internet Explorer web page.

Once installed, you can enable or disable the add-on by accessing the Manage Add-ons menu and clicking Enable or Disable Add- ons, which will open the Manage Add-ons dialog box. Any add-ons that are currently loaded in IE will be displayed in the Manage Add-ons dialog box, as shown in Figure 9.11.

Pop-up Blocker is a feature of IE that prevents pop-ups from being displayed by web pages. Pop- up windows are displayed on top of web pages and are often used by advertisers to display ads to visitors. However, not all pop-ups are advertising-related or malicious. Some web pages dis- play pop-ups to provide useful information.
By default, Pop-up Blocker is enabled. When visiting a site that displays pop-ups, a mes- sage appears in the Information Bar indicating that a pop-up was blocked. If desired, you can disable Pop-up Blocker by opening IE, clicking the Tools button, expanding Pop-up Blocker, and clicking Turn Off Pop-up Blocker. In the Pop-up Blocker dialog box, click Yes to disable Pop-up Blocker.
