When you remove a CA that is bundled with Firefox/Thunderbird, It 
disappear from the list on the current session, after you restart the 
application the CA still appear, if you press the "Edit Trust" button, 
you will see the CA is not trusted for anything. So Firefox is not able 
to remove the CA if it is bundled, but it remove all trust you have on 
it, so it will not be valid for anything
