Re:One hack I want (Score 1, Redundant)

So can Firefox, in most cases. Do "about:config", and set/add the network.negotiate-auth.trusted-uris string so that your domain is listed (e.g., I added lmco.com so that all domains ending in that string will auto-authenticate). This causes Firefox to process Kerberos tickets, to authenticate you to Active Directory. You may also want to set the network.negotiate-auth.delegation-uris string the same way, so that the web server can authenticate you to apps as well (e.g., like many portals do).
