Gecko

Gecko is the name of the layout engine developed by the Mozilla Project. It was originally named NGLayout. Gecko's function is to render web content, such as HTML, CSS, XUL, JavaScript, and render it on the user's screen or print it. In XUL-based applications Gecko also renders the application's user interface.

Gecko is used in many applications, including a few browsers such as Firefox and SeaMonkey (for a complete list, please refer to Wikipedia's article on Gecko). Products using the same version of Gecko have identical support for Web standards.
