Change time of day for Firefox updates

I am looking to find a way to change the time in which I receive updates from Mozilla. Getting an update interferes with the operation of my laptop and to top it off, I don't know that there is an update coming through so I waste so much time thinking I have a problem with my connection, my router, my settings, my laptop. Hugely inconvenient. Why can't I set the time I want updates to come through and not interfere with me while my laptop is in use. This is enough to make me want to drop Firefox and switch out.
