How do I create a setup that will not display the Add-on dialogue box when you launch Firefox. I do not want users to have the ability to install Add-ons.

It's one thing to change the setup process and quite another to completely disable a feature... Perhaps the links on this page will help at least with the first part: Deployment:Deploying Firefox - MozillaWiki.

Use a mozilla.cfg file in the Firefox program folder to lock prefs or specify 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:

You can use these functions in mozilla.cfg: 

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

To prevent users from installing software (extensions) use: 

lockPref("xpinstall.enabled", false);

Note that this may not work if files are dropped in a location where Firefox scans for new extensions.
