Webauth.comcast.net.443 uses an invalid security certificate
I use SeaMonkey to browse websites and it works fine. However, recently an error message continues to appear. It seems that this message does not appear in other browsers e.g. Internet Explorer, Opera or Firefox. The web pages display normally though the error message is very annoying.
I have contacted ISP Comcast to find any solutions and they do not help and simply ask me to use another browser like IE. Does anyone know that if the configurations or settings are incorrect? And what should I do to tackle the error? Thanks in advance.
