Silent Auto Update for Firefox ESR

Hi All- I am in charge of deploying Firefox ESR to my company and trying to get it to silently auto update on it's on with user interaction. We have policies in place (GPO) that prevent it at this point. I need some guidance on whether I should use just GPOs to manage this or should I go the route of the .cfg file? If someone has a step by step on how to best achieve this I would appreciate it. I am currently using the .msi installer. Here is settings in an old .cfg file that I am testing with: lockPref("app.update.mode", 1); lockPref("app.update.service.enabled", true); lockPref("extensions.update.enabled", false); lockPref("extensions.update.autoUpdateEnabled", false); // Set default homepage - users can change // Requires a complex preference defaultPref("browser.startup.homepage","data:text/plain,browser.startup.homepage=http://workday"); // Don't ask to install the Flash plugin lockPref("plugins.notifyMissingFlash", false); // Disable Search Engine automatic updates lockPref("browser.search.update", false); //Disable telemetry lockPref("toolkit.telemetry.prompted", 2); lockPref("toolkit.telemetry.rejected", true); lockPref("toolkit.telemetry.enabled", false); // Disable health reporter lockPref("datareporting.healthreport.service.enabled", false); lockPref("datareporting.healthreport.logging.consoleEnabled", false); lockPref("datareporting.healthreport.uploadEnabled", false); // Disable all data upload (Telemetry and FHR) lockPref("datareporting.policy.dataSubmissionEnabled", false); // Disable crash reporter lockPref("toolkit.crashreporter.enabled", false); Components.classes["@mozilla.org/toolkit/crash-reporter;1"].getService(Components.interfaces.nsICrashReporter).submitReports = false; // Don't show WhatsNew on first run after every update pref("browser.startup.homepage_override.mstone","ignore"); // Don't show 'know your rights' on first run pref("browser.rights.3.shown", true);
