It's a great idea, but for server farms like Google's, where there aren't any consistent certificates, it's simply going to numb you to the idea that certs are always changing.

Until the authors are willing to fix this—we've been complaining about it for years—it's worse than useless.

Great idea, and probably should be part of Firefox 4.x at some stage. Would definitely benefit from a whitelist for domains hosted on server farms whose certificates are jumbled and out of sync. See accountonline.com

This review is for a previous version of the add-on (1.4). 

I understand this is an important feature request. Guess a majority of users doesn't run into these websites but some just happen to have their accounts at a certain bank or similar. I would prefer these companies would fix their certification policy, but that's probably wishful thinking.
