I would like to add a line to prefs.js - is there a way to write a batch file to do that?

user_pref("network.automatic-ntlm-auth.trusted-uris", "hostname");

Put that pref into a user.js file.

Firefox looks at the user.js file every time it starts for additions or changes to preferences, and then writes those to the prefs.js file.

user.js doesn't exist by default, it has to be created. This extension will create that file automatically upon installation and it provides an editing window for the three "user" files from within Firefox. You don't have to dig thru your file system every time you want to do a minor edit.
