I want to 1. Take my existing set-up of Firefox

         a.  with all bookmarks
         b.  with all my chosen options
         c.  with my default start-up home page
         d.  bypass all the initial Firefox startup screen and "make this your default screen" 

2. Have it be the base set-up for all users that log into a machine on our domain.

Is there a config file? Where do I place this config file so when all open their firefox it takes the above settings. I am creating a base image using VMware and will want this set-up so when a user log in with their logon credentials and open Firefox, it already has the above mentioned settings in place.

You could probably make a copy of the Firefox profile you use in the config you have set up.

Please check out this page on how to backup and restore information in Firefox profiles: http://mzl.la/LHJo6V

See CCK Wizard: https://addons.mozilla.org/firefox/addon/cck/

You can use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values.

Place a file local-settings.js in the defaults\pref folder where you also find the file channel-prefs.js to specify using mozilla.cfg.

pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift

See:

These functions can be used in the mozilla.cfg file:

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