I manage workstations for an enterprise and I've noticed that Firefox is unable to update itself automatically or manually from within Firefox; however, I can manually download the Firefox installer from https://www.mozilla.org/en-US/firefox/new/ and apply the latest update with a new installer. I suspect that our corporate firewall must be blocking whatever URL Firefox is connecting to in order to self-update. Unfortunately I haven't been able to find this URL documented anywhere in order to whitelist it. What URL does Firefox connect to in order to update itself? Thank you for your time and assistance and have a great Friday!
