    Bug 12974: Disable NTLM and Negotiate HTTP Auth
    
    This is technically an embargoed Mozilla bug, so I probably shouldn't provide
    too many details.
    
    Suffice to say that NTLM and Negotiate auth are bad for Tor users, and I doubt
    very many (or any of them) actually need it.
    
    The Mozilla bug is https://bugzilla.mozilla.org/show_bug.cgi?id=1046421
