El objeto window representa la ventana que contiene un documento DOM; la propiedad document apunta al DOM document cargado en esa ventana. El objeto window al que pertenece un documento puede ser obtenido usando la propiedad document.defaultView.

Esta sección proporciona una pequeña referencia a todos los métodos, propiedades y eventos disponibles a través del objeto DOM window. El objeto window implementa la interfaz Window , que a su vez hereda de la interfaz AbstractView. Algunas funciones como globales adicionales, espacios de nombres, interfaces, y constructores no típicamente asociados con el objeto window pero disponibles en éste, están listados en las Referencia de JavaScript y en el Referencia DOM de Gecko.

En un navegador con pestañas, como Firefox, cada pestaña contine su propio window object (y si está escribiendo una extensión, la ventana del navegador es una ventana separada también - para más información vea Trabajar con ventanas desde el código chrome). Esto significa que el objeto window no se comparte entre diferentes pestañas de la misma ventana del navegador. Algunos métodos, como window.resizeTo y window.resizeBy se aplican sobre toda la ventana del navegador y no sobre una pestaña específica a la que pertenece el objeto window. Generalmente, cualquier cosa que razonablemente no pueda pertenecer a una pestaña, pertenece a la ventana.
