Hi team,

Today I'm receiving a continuous advertisement from my AVG Ultimate antivirus that FireFox web browser is having a security problem due a Malvertising that is launch from url: http://detectportal.firefox.com/canonical.html

My antivirus show it constantly, independent if I'm in the home page, or in the setting page of firefox for MAC.

Do you know what can be the cause of this problem? Is it possible to fix?

I scan all my computer and is free of virus, also my antivirus is up to date and I'm using professional version.

I send you an screenshot of message that appears.

Thanks in advance and best regards,

Hola Como indica en la pagina de ayuda de Mozilla: https://support.mozilla.org/es/kb/captive-portal El Firefox realiza conexiones a http://detectportal.firefox.com/canonical.html para determinar si la conexión a internet es mediante un "portal cautivo" que suelen ser redes de Wifi publicas, esta conexión se realiza para poder saber si el usuario debe iniciar sesión nuevamente en el portal cautivo luego de cambios de paginas mientras navega. En caso de no utilizar portales cautivos puedes dejar dichas conexión bloqueadas en el antivirus y deshabilitar la prueba del Firefox como se indica en la respuestas de la siguiente consulta: https://support.mozilla.org/en-US/questions/1157121

Si se ha resuelto la consulta agradeceríamos marcar como solucionada para que sirva a otros usuarios. ¡Gracias!
