The template is outdated and does not match many of the settings, but it was easy to add settings to the .adm template. I do not like this method since I have to install the addon (somehow) on all of the computers. Also, there are a couple of settings I need to configure (such as privacy.sanitize.promptOnSanitize", false) that are not currently in the 'about:config' by default and the GPO does not create them.

   So, I have been trying to figure out the other method of configuring Firefox settings in an enterprise environment, and have been working mostly with these articles:

   I figured once I have the mozilla.cfg and local-settings.js configured, I can copy them to all of the computers with a script, instead of having to install the GPO AddOn. Here's what my local-settings.js looks like:

//
pref("browser.startup.homepage", http://www.msn.com);
lockPref("browser.startup.homepage", http://www.msn.com);
pref("security.tls.version.max", 1);
lockPref("security.tls.version.max", 1);
pref("security.tls.version.min", 0);
lockPref("security.tls.version.min", 0);
pref("security.default_personal_cert", Ask Every Time);
lockPref("security.default_personal_cert", Ask Every Time);
pref("app.update.enable", false);
lockPref("app.update.enable", false);
pref("browser.search.update", false);
lockPref("browser.search.update", false);
pref("extensions.update.enabled", false);
lockPref("extensions.update.enabled", false);
pref("network.protocol-handler.external.shell", false);
lockPref("network.protocol-handler.external.shell", false);
pref("plugin.disable_full_page_plugin_for_types", PDF, FDF, XFDF, LSL, LSO, LSS, IQY, RQY, XLK, XLS, XLT, POT PPS, PPT, DOS, DOT;
lockPref("plugin.disable_full_page_plugin_for_types", PDF, FDF, XFDF, LSL, LSO, LSS, IQY, RQY, XLK, XLS, XLT, POT PPS, PPT, DOS, DOT);

   However, when I copy the mozilla.cfg file to C:\Program Files (x86)\Mozilla Firefox\ and the local-settings.js file to C:\Program Files (x86)\Mozilla Firefox\defaults\pref it has no effect on the settings in Firefox. I can go to about:config and see nothing has changed. 
   Any help is appreciated!

I need to lock a bunch of preferences so they can not be changed by users on multiple Windows 7 computers running Firefox. I was able to get most of the settings I needed locked down in a test environment by using the Firefox-GPO-Addon and an .adm template I found online: https://addons.mozilla.org/en-us/firefox/addon/gpo-for-firefox/ The template is outdated and does not match many of the settings, but it was easy to add settings to the .adm template. I do not like this method since I have to install the addon (somehow) on all of the computers.
