I'm trying to sign in to hotmail but nothing happens. Web console shows next message:
Status Code:
  HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied.  )

I cannot reach https://google.com as well. By the way I cannot reach https://bugzilla.mozilla.org/ as well. If I'm typing thous links in address bar nothing happens at all.

https links worked fine in firefox 3.6 (in firefox 4b4 as well I suppose but I'm not sure).

My computer is in the Active Directory domain.

Reproducible: Always

Steps to Reproduce:
1. Go to hotmail.com
2. Try to sign in

Actual Results:  
Nothing happens

Expected Results:  
I'm signed in.
