Mozilla Firefox: Disable Auto Update

This one took me a little bit of work to piece together and get right and working, but finally got it working. 

If you find this post in anyway helpful, please leave a comment and also consider leaving a small donation.

I was doing this for a client to stop auto updates on their Terminal Service / Citrix servers which was regularly faulting due to the update.

The steps below guide you through setting the configuration files required for Firefox to not only turn off updates, but deny the setting entirely.

Also note, this is on a per computer basis. This process will need to be replicated on each computer/server as necessary or desire.

Note: The install directories used here is default for a Windows 64-bit operating system. You install path may different.

  1. Create file local-settings.js in C:\Program Files (x86)\Mozilla Firefox\defaults\pref
  2. Copy the following and save in file
pref("general.config.obscure_value", 0);
pref("general.config.filename", "mozilla.cfg");

  1. Create file mozilla.cfg in C:\Program Files (x86)\Mozilla Firefox
lockPref("", false);
lockPref("app.update.enabled", false);

  1. Test and confirm access

You can confirm this by going to the Perferences and Update tab and find that the update options are greyed out. Alternatively, browse to about:config and the above options will be in Italics.
