Currently I am using ESR 52.7.0 and planning to move to ESR 60.1.0. However, during test I found that Mozilla.cfg file is not read by ESR 60 series but the same is working fine with before ESR 52 series

In ESR 60, the configuration formats has been changed when compare with ESR 52 series. So, Could you please help us how to make customization for Firefox ESR like homepage, app update disable and other settings

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.
