I'm seeing this on beta 5 as well.  Are you using a proxy with NTLM authentication?

Using Wireshark, I'm seeing Firefox attempt to CONNECT with the proxy with a 407 (Proxy Authn Required).  In comparison, IE gets a 200 (Connection established).

The difference appears to be that Firefox is omitting the Proxy-Authorization header in the CONNECT request.

Yes, I am working inside my company intranet and need to go through a proxy server with NTLM authentication.
