I've never heard any plan to have silent updates mandatory. Though they will be on by default on Windows if the installation is done with enough privileges to allow the Service to be installed, silent updates won't be mandatory. Also Firefox will not bypass OS dialogs, the user will have to give the service the authorization once, at installation time, that's all. Then the OS won't throw other dialogs.
I'm curious if you have to go and disable the service or go into options to turn it off.
