Rated 5 out of 5 stars

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.
