What are pop-ups?
Pop-ups are windows that appear on top of a web browser window without your permission. Pop-ups are often used to display advertisements, but sometimes pop-ups are used to display or obtain useful information such as a user name.
Pop-up Blocker Instructions
By default, most web browsers automatically block pop-ups using a pop-up blocker. You can choose to turn off the pop-up blocker or allow pop-ups for specific sites.
