How do browser add-ons affect my browsing experience?
Add-ons, also known as ActiveX controls, browser extensions, browser helper objects or toolbars, can improve your experience on a website by enabling content such as high-quality animations. However, some add-ons can also malfunction or display content that you don’t want, such as pop-up ads.
When an add-on, such as a toolbar, is installed on your computer, it becomes part of your browser and operating system. In some cases these programs might contain spyware. In the worst case, a malfunctioning add-on might affect the performance of your computer or cause problems accessing the Internet.
