Pop-ups are windows that appear automatically and without your permission. They often display advertising that can interfere with your ability to see the content on the page you're trying to read.
A pop-up blocker works with your Internet browser to prevent pop-up windows from automatically opening when you visit a web site. Unfortunately, blocking all pop-ups may prevent important features. ADP recommends that you turn off any pop-up blockers while using this application.
You can turn on and off most pop-up blockers at any time.
