If software could reliably know when the setting was changed--<p>--It could warn the user: Hey, isn&#x27;t it convenient that this check was disabled just before this addon was about to be installed?<p>Perhaps a three strikes approach, where, if you disabled the warning, you&#x27;d still have to suffer through the warning three more times. You&#x27;d need a reliable way to store the state to avoid tampering.
