There are some certs that are pinned (tor's site is one I remember) and 
you can't override those easily. If you have removed the default CAs 
and run into this you have to go somewhere esle in the config to unpin 
the certs for the special sites. I don't remember all of the details, just 
that I needed to do it to be able to visit the tor site again.
