"...how to get Firefox to do NTLM, which means I don't have to deal with the authentication dialogs, thereby reducing my dependence on IE

...

It's not at all obvious how to make it work, and it took me a few tries. You have to go to your Firefox address bar and type about:config. This will bring up the internal config editor, which allows you to set all kinds of properties that influence Firefox's behavior. Look for the key called network.automatic-ntlm-auth.trusted-uris. Set that key's value to a comma separated list of servers you want NTLM auth for. So if your internal SharePoint sites are on servers called Larry and Mo, use "larry,mo". You can also add the same value to the key network.negotiate-auth.trusted-uris. It's unclear to me if that second one is required, but I set it, and everything works. Now SharePoint works like a champ, and authenticates automatically."

Something to try when I return to the office....
