Weird error message

[m_artist200]

I started up firefox, and got this wierd message.....I can't remember it completely, but it went along the lines of

"*something about a certificate and checking its CN*. If this certificates CN is not xxxxxxx it is unlikely but possible someone is trying to intercept information from your computer. If the CN is not xxxxxxxx please disable your connection and contact your web administator" or something like that.

What is was...something from mcafee (i use a mcafee siteadvisor) and the CN didn't match up...(it was like supposed to be C100-000 *something) but the 1 was a 2.

Anyone have any idea what this is? Something I should be worried about?

It's not an error, nor do you have anything to worry about. Seeing how it is near midnight out here I really don't feel like explaining it.

Just click, "accept certificate permanently".
