Firefox is used on Windows 11 Enterprise. There is a firefox.cfg in the installation directory (and an autoconfig.js in the ./defaults/pref sub-directory). The firefox.cfg targets an autoconfigfile.js. This setup is recommended here: [firefox using autoconfig"]

  1. In the support article´s example, the firefox.cfg uses a pref(); expression. Is it possible to use a lockPref(); expression instead?
  2. What is the result of either using pref(); expressions or user_pref(); expressions in the remoted autoconfigfile.js? Are both of them possible, especially while the firefox.cfg uses lockPref(); expressions instead of pref();?

I hope that somesone can help with one of these questions. Thanks a lot!

The cfg files and a regular pref file are two completely different things (event though the syntax looks similar at first glance)

The CFG file is running Javascript and calling functions to execute the various things (like lockPref).

The autoconfigfile.js is a specific JS file format used for storing preferences.

To answer your specific questions.

1. Per that article, you can use any of the functions in a CFG file like pref, lockPref, defaultPref, etc. 2. In a regular JS file, pref sets a default pref (defaultPref in an autoconfig file) and user_pref sets a user preference (pref in an autoconfig file)
