I did search the internet. Firefox did not give me the option to choose when to install, it did it automatically. Look at my screen shot. I thought you guys would be helpful. That is why I came here. The choice of "choose when to install" is not true. I am not the only one who has this problem.

As a user I wanted to get rid of the update notifications, and Since taking the following steps on my Win10 machine, Firefox has neither notified me of an update, nor installed one automatically. I have to manually check for updates, and then manually initiate them.

Close Firefox. Go to your Firefox install folder for (e.g. "C:\Program Files\Mozilla Firefox") and then go to the distribution folder within this (if it doesn't exist create it). Inside this distribution folder, create a policies.json file. So now you will have a file with the address, for e.g. "C:\Program Files\Mozilla Firefox\distribution\policies.json" Paste the following 5 lines into this policies.json file:

{
  "policies": {
    "ManualAppUpdateOnly": true
  }
}

@TechHorse, try < pre >your code< /pre > (without the blank spaces).

Thanks Terry, formatting now fixed.

On another note, I think that the 'let me decide when to install an update' option only means in practise 'let me decide when to download an update'?

Once you have chosen to download, Firefox will then install the update at the soonest appropriate time, with no further user confirmation sought?
