Mine prompts me to restart when I load a new page, no option to postpone as fat as I've seen.

  The option is here: about:preferences#general ("Check for updates but let you choose to install them", if English localization)

    That pref is not present because it does not apply to distro updated Firefox such as a .deb.

  Because postponing isn't possible, the files changed from under it and their behavior is undefined.
