Certificate Patrol - A Firefox Add-on

Certificate Patrol

What it does?
When you visit a https encrypted page it will download and store the information available on the certificate used on the server. If in the future the certificate changes, you will get a warning stating this fact and the reason why the certificate changed.

Why I need this?
You probably remember a recent story about forged certificates. An attacker was able to obtain forged certificates for high profile sites like Google and Microsoft. These forged certificates combined with a man-in-the-middle attack (for example) could result in making you think you are accessing a legit site, using a secure connection while in fact this is not true. Such certificates do get revoked (they are no longer valid) but the revocation process takes time. With this plugin you will be warned that the certificate has changed and unless there is a legitimate reason for this change to happen (the old certificate expired, for example) you have a reason to be suspicious.

I think it is a good idea that maybe should be a default feature of all browsers.

So I used this addon I try to sign in Facebook since its activated in Https it will show a popup on the top and you can view details about the certificate that was use in https.

Yes, and if the certificate used to encrypt the connection changes without a valid reason you will receive a warning.
