How to lock down Firefox in an Enterprise Environment?

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   The template is outdated and does not match many of the settings, but it was easy to add settings to the .adm template.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. 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:

http://stealthpuppy.com/prepare-mozilla-firefox-for-enterprise-deployment-and-virtualization/
http://kb.mozillazine.org/Locking_preferences

   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("general.config.obscure_value", 0);
pref("general.config.filename", "mozilla.cfg");

And here's my mozilla.cfg file, with some of the settings I need configured:

//
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!

An advertisement appears on the to of the majority of web pages. It is always accompanied by the words "Ads not by this site". In some cases the area consumed by this add removes data from the bottom of the page and can not be recovered. This "feature" has appeared two days ago and I have tied, without success, to disable it.

When viewing a user's photos on instagram.com/user, I click on one photo and it opens in a new tab (as opposed to popping up in the same tab in middle of the screen). Then, when I 'X' out the new tab and return to the old one with the rest of the photos, I cannot click on anymore. I have to refresh the page each time I want to view a new photo. This does NOT occur when I view the instagram.com/user page using Internet Explorer. Shockwave Flash and all other plug-ins are up to date. I just noticed this issue with Firefox's newest upgrade.

Hi guys,

Since last Mozilla update to version 23.0 my check-spelling isn't working anymore. I seem to be miss-writing every word, as all of them are being underlined.

How do I solve this problem? I do not want to change to another crappy browser just because I can't use a check-spelling add-on...

Just as a side note, this whole thing was working on version 22, and I don't quite understand why it isn't now. I just want to see this fixed, please help? Thanks in advance.

Hi! I use your awesome browser as my #1 browser. Since the most recent update, however, I can not see content on Facebook that was available (and works on all other browsers).

Here is a link where you can see it working on all other broswers but not FF:

https://www.facebook.com/pages/The-Gables-Inn/91848818163?id=91848818163&sk=app_243138959111822

It in an iFrame FYI.

I have developed over 3000 FB pages and now they only work in the other browsers. I have gotten most of my clients to instal FF so this is an even bigger issue. I am out of ideas. Please let me know if its me or what to do to make it work.

Thank you so much!!!!

every page on every open tab refreshes every 30 seconds and each time it is saved in my cache. If I want to go back to a previous page, I have to click back once for every 30 seconds I was on the current page. Very annoying!! It just started doing this recently and I don't know why. I did reset the about:config to "0", but that didn't help.
