Following this question about Windows Domain Authentication with Firefox, does FF support using wildcards in the URI's? I'm not finding anything where it mentions support either way.

  • Have you tried it?

  • So that means it doesn't work then? Or does it?

    Sorry, thought that would be clear since I'm asking. No, my efforts didn't work. I was looking around to find out if FF just simply does not support it or if maybe my wildcard syntax was just wrong.

    I was interested in this because I wanted to support any port on localhost. As it turns out, just http://localhost works fine. Jul 19, 2011 at 22:23

Just to expand on redbeard0x0a's answer, it seems that it's matching based on the end of the string, not a sub string. So, if you have a company domain like "mycompany.com" with servers like svn.mycompany.com, sharepoint.mycompany.com, mail.mycompany.com, you could modify the network.automatic-ntlm-auth.trusted-uris within about:config to:


or just include them all and any other internal servers by doing:


  • Note that you need at least on dot for it to be a wildcard. So if you can host1.hr.europe.company1. Then company1 will not work, you need to put europe.company1. I guess if there is no dot firefox assumes it's a hostname not a domain name. May 5, 2010 at 8:53

    I think you'll want to use ".mycompany.com", leaving that leading dot out would match "notmycompany.com".

  • @David @davenpcj I wish I could use example.*, i.e. example.com, example.net, etc Jan 24, 2011 at 9:05
  • Just to add to this, I found that mycompany.com had to be at the end of the list if I had any more specific entries. For example http://localhost,.mycompany.com worked, but .mycompany.com,http://localhost did not work. Mine is now working fine, but I hope this helps someone.

I don't know if I understand the question correctly, but I'm thinking you are trying to use a wildcard in the network.authentication-ntlm-auth.trusted-uris inside firefox's config.

I think everything is matched on a sub-string (internally it seems to work like *example.local*, so having the domain example.local you would put example.local in the configuration, for example: localhost,fileserver,example.local.

If you end up having a url of http://server1.example.local/, it should trigger the example.local entry for trusted-uris and seamlessly send over NTLM authentication.
