This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80.

Al mantener una referencia a la función eval() desde una ventana about:blank, una página web maliciosa podría haber conseguido acceso al objeto InstallTrigger, lo que le permitiría solicitar al usuario que instale una extensión. Combinado con la confusión del usuario, esto podría resultar en la instalación de una extensión maliciosa o involuntaria. Esta vulnerabilidad afecta a Firefox versiones anteriores a 80, Thunderbird versiones anteriores a 78.2, Thunderbird versiones anteriores a 68.12, Firefox ESR versiones anteriores a 68.12, Firefox ESR versiones anteriores a 78.2 y Firefox para Android versiones anteriores a 80
