Mozilla has been very destructive, and I have had to restrain Firefox in a number of different ways. It's Updater.app will disregard your wishes and repeatedly download updates over and over again. This happened to me when I had to turn in an assignment and I was on a 2G connection a few years ago. Most of their updates are unidirectional, even though they don't need to be. And major features are quietly removed, as if it is just normal for your car's speedometer to disappear one morning. This ends up feeling like gas-lighting. At least Chrome's updates are small and hard to notice, but Firefox has all the same disregard for users, except they are very clumsy about it. And the official response from them has been that if their updates destroy your profile folder, that you should have made a backup and it was your fault for assuming that their software wouldn't do a destructive update.
