This Connection is Untrusted

You have asked Firefox to connect
securely to forum.videolan.org, but we can't confirm that your connection is secure.

Normally, when you try to connect securely,
sites will present trusted identification to prove that you are
going to the right place. However, this site's identity can't be verified.

What Should I Do?

If you usually connect to
this site without problems, this error could mean that someone is
trying to impersonate the site, and you shouldn't continue.

Technical Details

does the certificate will automatically passes the authentication, i mean then we will not have to see that warning, for all the sites without this certificate.

sorry for my bad english.
but i am trying to say that, suppose we install the certificate, and we use videolan, hats ok, we know its not a bad site.

but what about those bad sites which firefox alerts us on genuine, installing this certificate will pass authentication as a whole to other bad site also??????
