Mousetrapping is a technique used by some websites to keep visitors from leaving their website, either by launching an endless series of pop-up ads—known colloquially as a soggy biscuit—or by re-launching their website in a window that cannot be easily closed (sometimes this window runs like a stand-alone application, and the taskbar and the browser's menu become inaccessible). Many websites that do this also employ browser hijackers to reset the user's default homepage.[1]
