As you can see, it is a very large topic.

The below are few setting which i want to customize for ESR 60 using mozilla.cfg and local settings. All the settings were working fine with till ESR 52 series but not with ESR 60

//Homepage set pref("browser.startup.homepage", "https://google.com");

// Enabbles remembering passwords lockPref("signon.autologin.proxy", true);

// Disables browser search update lockPref("browser.search.update", false);

// Lock preference for auto update lockPref("app.update.enabled", false); lockPref("app.update.service.enabled", false); lockPref("app.update.disable_button.showUpdateHistory", false);

mozilla.cfg should work in Firefox 60 ESR the same way as in Firefox 52. In Firefox 60 you can check the Browser Console for error messages.

I also have this issue; however, it seems to be limited to installation of ESR-60 (and above) on Windows platforms. With ESR-52.9 (and older) the files which I placed into "Program Files\Mozilla Firefox\defaults\prefs\local-settings.js" and "Program Files\Mozilla Firefox\mozilla.cfg" are able to make settings and lock preferences. The settings which I used in the files are similar to those listed by shekpal. When I use the same files, in the same locations with ESR-60 (and above) installed on Windows 7 or Windows 10, when I open about:config, the settings are either listed as "user set" or "default" and can be changed. That is not desired behavior. I have also placed the same files into installation of ESR-60 (and above) on Linux installations (as "/usr/lib64/firefox/mozilla.cfg" and "/usr/lib64/firefox/defaults/preferences/local-settings.js") and the locked behavior is as desired--about:config shows the settings as locked. I followed the steps in https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig to completely reset and used the names of autoconfig.js and firefox.cfg. I ensured that the first line was a comment. Nothing restored the desired functionality on a Windows system. An additional anomaly which I did find is that if I have "Program Files\Mozilla Firefox\defaults\prefs\local-settings.js" in place without the referenced mozilla.cfg file in place gives these results: Firefox 52.9-ESR displays an error that preferences cannot be found and closes. That is expected behavior. Firefox 60.3-ESR opens without displaying an error.
