A pop-up ad is a small ad that opens during a web browsing session without the user choosing to open it. Pop-ups most-commonly open when another page opens. Since pop-up ads can be annoying, most web browsers include a pop-up blocker. Because browsers operate in different ways, the method to turn on the pop-up blocker depends on the browser being used. Three of the most commonly used browsers that have integrated pop-up blockers include Internet Explorer, Firefox and Safari.
