You can't disable it installing new extensions behind your back without telling you, though. These are "system extensions" and you can't opt out of them.

  System extensions are not really extensions, they're just parts of built-in browser functionality that have been implemented by programmers with good code hygiene. It's unfair to describe these as "installing random extensions without asking" because you would then have to admit that it's equally true of every new feature of every software program that is ever updated.

    I don't think it's unfair; I can disable automatic software updates. I can't disable Firefox installing secret extensions behind my back.

      That is a logically incoherent statement. The only mechanism Mozilla has for "installing secret extensions" is via software updates. If you turn that off, they can't install anything.

        At least with Firefox you can disable both individual extension updates and browser updates. Chrome on the other hand removed that option years ago. Deleting Chrome Update's scheduled-task is my workaround. I don't recall if extension updates can be disabled in chrome.
