Pop-up ads or
pop-ups are often forms of online advertising on the World Wide Web intended to attract web traffic or capture email addresses. Pop-ups are generally new web browser windows to display advertisements. The pop-up window containing an advertisement is usually generated by JavaScript using cross-site scripting (XSS), sometimes with a secondary payload using Adobe Flash,but can also be generated by other vulnerabilities/security holes in browser security.
A variation on the pop-up window is the
pop-under advertisement, which opens a new browser window hidden under the active window.
Pop-unders do not interrupt the user immediately and are not seen until
the covering window is closed, making it more difficult to determine
which web site opened them.
Opera was the first major browser to incorporate tools to block pop-up ads; the
Mozilla
browser later improved on this by blocking only pop-ups generated as
the page loads. In the early 2000s (decade), all major web browsers
except
Internet Explorer allowed the user to block unwanted pop-ups almost completely. In 2004, Microsoft released Windows XP SP2, which added pop-up blocking to Internet Explorer.
Most modern browsers come with pop-up blocking tools; third-party tools tend to include other features such as ad filtering.
