Changing the default channel-prefs.js
i have been given task to change config for Mozilla ESR users in our company. I'm trying to change the value "security.enterprise_roots.enabled" which is disabled by default in update channel "esr". Is it safe to push (mass copy) new file "channel-prefs.js" with modified preference or there is another way?
pref("app.update.channel", "esr"); /* extra code */ pref("security.enterprise_roots.enabled", true);

No you shouldn't modify this file, but instead use a mozilla.cfg file in the main Firefox program folder.
The mozilla.cfg file needs to be in the main Firefox program folder.
These functions can be used in the mozilla.cfg file:
defaultPref(); // set new default value pref(); // set pref, allow changes in current session lockPref(); // lock pref, disallow changes
This requires a local-settings.js file in the "defaults/pref" folder where the channel-prefs.js file is located that specifies to use mozilla.cfg.
// pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0);
The mozilla.cfg and local-settings.js files need to start with a comment line (//).
