Enable NTLM Authentication in Firefox

Problem
Need to be able to perform NTLM Authentication for Single Sign-On Integrated Authentication using Firefox browser.

Solution
Create a whitelist in Firefox settings (about:config) by adding comma delimited list of domains to network.automatic-ntlm-auth.trusted-uris

Example: myintranet, www.mydomain.com, etc

Can't Delete Firefox Bookmark Tags

Workaround to delete tag that will not go away:

1) Remove tag from all known bookmarks
2) Type tag in location bar (for me, an old bookmark appeared with tag applied)
3) Select location
4) Bookmark location by clicking on the star
5) Click on star again and select "Remove Bookmark" button.

Location bar search

Excerpted from:
http://support.mozilla.com/en-US/kb/Location+bar+search

If you enter text into the Location bar that is not a valid Internet address (URL), Firefox will try to direct you to the location you intended.

Internet Keyword search

1. about:config
2. keyword.enabled
• false disables Internet Keyword searches.
• true enables Internet Keyword searches.
  

Domain Guessing

1. about:config
2. browser.fixup.alternate.enabled
• false disables Domain Guessing.
• true enables Domain Guessing.
