Stop firefox from updating
I made the mistake of letting Firefox update itself to the latest version, and so I lost all my valuable extensions.
In this tutorial, you will learn how you can control the auto updates of your browser? Now every new version of Mozilla Firefox is coming with Automatic updates enabled by default.
These versions can be used to delay getting new features while still maintaining security.
You should use one of these instead of a newer, old, non-ESR release such as Firefox 56.
2 - download minor updates only, prompt for major updates, regardless of whether or not all enabled extensions are compatible.
an upgrade to quantum is definitely a major upgrade...
