Firefox: How to enable automatic authentication/login using ntlm (Sharepoint and others?)

If you don't like to use IE due to whatever reasons and hate to have to login to your business webpages, where IE just works but firefox always nags you with a login prompt.

Get rid of it now, this is how:

• Open firefox, type in the address bar about:config
• acknowledge that you are aware of loosing your warranty
• type in the search pane uris
• Change the value of the two ...trusted-uris Preference Names found (see screenshot below) to a comma separated list of the domains or hosts you want, e.g. mydomain.com,myotherdomain.com

If you access a server with only the hostname, e.g. you put in the address bar mysharepoint, you will get prompted with a login box. To avoid this add the hostname also to the comma separated list.

example:   ad.domain,companyweb.com,mysharepoint

If you access mysharepoint now it will not ask for the login credentials and also not if you try to access mysharepoint.ad.domain.

Have fun.
