    • Add-ons: include tools that enhance your browsing experience, such as toolbars or programs that block pop-up ads from opening.
  • 4. Enhancing Your Use of the Internet with Browser Extensions
    • Helper applications are independent programs that are stored on your computer and are activated automatically when needed.

    • Plug-ins do their work inside the browser and do not activate a standalone program that is stored on your computer.
    • When you install a Web browser, many popular plug-ins are often installed with it.
