Weird, maybe your internet, maybe something wrong with your install depends on whats going on. Google shouldn't be showing that. whats the HTTP error code?

There is no error code, only the message I've quoted. The heading is:

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

This problem dates only from this morning when I booted up. And I can still get Google on Internet Explorer. It makes no sense at all to me
