Install and Configure Firefox 106 silently using SCCM

The following steps show how to create a silent install package of Firefox, complete with custom configuration.

It does the following tasks:

  • Install Firefox silently, without Firefox being the default

  • Disables the ‘Always check to see if Firefox is the default browser on startup’ option
  • Sets homepage to ‘’ (you can change this in your configuration)
  • Disables the ‘know your rights’ button from displaying on first run
  • Disables the request to send performance data from displaying

  1. For the comments having a configuration error: The general error is trying to set an integer preference when the preference is actually boolean. If you’re unsure, check the preference on a clean install without any policy – if it is ‘true’ or ‘false’ then use:


    If the preference is a string:

    lockpref(“”, “stringHere”);

    If the preference is a number:

    lockpref(“”, 2);

    All lock pref can be changed to ‘pref’ instead if you don’t want to set & lock the preference all at once.

  2. I have the problem with Version 33 that none of my settings will be applied.
    So all files are existing, but nothing of the mozilla.cfg is changed in my current settings if I check it in the about:config.

    Any ideas? Was something changed in the new version?

  3. Hello all, I have this script implemented and it works, however I updated to ver 33.0 of firefox which now by default hides the Menubar (irritating) and I need to find the setting to have it always show and set it as a defaultpref. I’ve tried a few variations of some things I’ve found in the about:config file but that only seems to work for the user it’s installed for and not other profiles, anyway to have it show always for any user??? Thanks.
