Great information! Rated 5 out of 5 stars
I love this extension for the ability to show all the neat little extra information I want to know about my SSL connection with sites where I'm using 'https'.
My only quip is that the layout should be multi-lined because I have it dump out so much information that it gets truncated in newer versions of Firefox because the layout has changed for the SSL window (when you click the padlock) in Firefox 41+.
Still an amazing extension. Power users should definitely use this!
