  Certificate Patrol

  If you're concerned that not all SSL Certification Authorities are to be trusted, this is a Firefox plugin to try. It locally caches all certificates it has seen so far, and issues a warning whenever it sees one for the first time, or when something has changed and it's not clear why. This comes with some false positives though, as some major sites use different certificates for the same domain name.
