I need to do a silent install that installs preferences on the specific machine.

I am writing a silent install for corporate use. I have used the -ms switch to get the installer working.

However, there are several options that I need to automatically update using the prefs.js file. (The most important is to turn off the three automatic updates, but there are also other prefs.js changes that affect speed and browsing environment.)

The problem is that this is stored in a %APPDATA%\Mozilla\Firefox\Profiles\<profile folder>

but this folder is not created until after the first login. By then the user has already set other defaults.

The question is how can I run the install to include these necessary defaults?

You can initialize prefs in two ways. Via an mozilla.cfg configuration file or via a user.js file in the default template location (C:\Program Files\Mozilla Firefox\defaults\profile\user.js)

See http://kb.mozillazine.org/Locking_preferences

You can use these functions in mozilla.cfg: 

defaultPref(); // set new default value
pref();        // set pref, but allow changes
lockPref();    // lock pref, disallow changes
