15 1. Start Firefox and open the advanced settings by entering //about:config// into the address bar, and press enter.
16 1. Firefox now warns you that this might void your warranty. Click on //I accept the risk!//.
17 1. Use the search bar to search for //ntlm//.
18 1. Click twice on the entry //network.automatic-ntlm-auth.trusted-uris// to modify its value.
19 1. Enter the server address of the NTLM server in the dialog that opens. If you want to enter more than one server, do so by separating them with a comma. For example: //http:~/~/myserver_1, http:~/~/myserver_2//. In case you want allow an entire domain, this can be achieved like this: //http:~/~/.myDomain.dom//. Wildcards such as a star ({{{*}}}) or a question mark ({{{?}}}) are not supported.

26 1. Click twice on the entry //network.negotiate-auth.allow-non-fqdn//, if its value is not set to //true// already. It should now be set to //true//.

41 The profile name is a random string consisting of 8 letters and digits. When the settings have not yet been modified via the configuration page, they can be added with the following batch script. Firefox should be closed when executing the script.
