commit 4825026471678728d5aa085717e301fc6551fe2b Author: Mike Perry <mikeperry-git@torproject.org> Date: Wed Aug 27 15:19:10 2014 -0700 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.
