The title of the popup lacking an address bar should not be fully controllable, but in this situation was.

El t\u00edtulo de la ventana emergente que carece de una barra de direcciones no deber\u00eda ser totalmente controlable, pero en esta situaci\u00f3n s\u00ed lo era. Esto podr\u00eda haber sido usado para falsificar un sitio web e intentar enga\u00f1ar al usuario para que proporcione credenciales. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 78.9, Firefox versiones anteriores a 87, and Thunderbird versiones anteriores a 78.9"
