To whom it may concern I am testing the autoupdate on one of my vm`s and I cannot configure what we need. Goal: - We would like to update firefox esr yearly with a package through sccm. - After installation or after first startup, firefox should imediately update to newest version - From then, firefox esr should installed newest version as soon as available and check daily for a new version My Config: // Enable updater lockPref("app.update.enabled", true); lockPref("app.update.auto", true); lockPref("app.update.mode", 0); lockPref("app.update.service.enabled", true); lockPref("app.update.silent", true); lockPref("app.update.timerFirstInterval", 60); lockPref("app.update.promptWaitTime", 60); lockPref("app.update.download.backgroundinterval", 0); lockPref("app.update.doorhanger", false); lockPref("app.update.disable_button.showUpdateHistory", false); The config file was implemented. I could see the changes in about:config, but if I today distribute version 78.7.1 with the above config file, firefox esr does not automatically update to the newest version 78.8.0. Only if I open the settings or the help about. What am I missing? How can I achieve that firefox will update silently(without user intervention) imediately to newest version after install and update regularly to newest version? Regards, Jonas
