Based on my reading of https://support.mozilla.org/en-US/kb/what-mozilla-maintenance-service https://support.mozilla.org/en-US/kb/what-mozilla-maintenanc..., the current behavior is that Firefox checks for updates only when the app is open, and then only briefly starts the MozillaMaintenance service to avoid the UAC dialog. The MozillaMaintenance service isn't what is responsible for checking for updates. It's not clear to me if MozillaMaintenance is the service that will be checking for updates, or if there is a new service.
