A simple addon ? It's not simple for modern day users , blocking scripts ? Well good luck with that , all those modern bloated websites simply won't work , even if user knows what he's doing. Try to use NoScript here , for example . You won't even be able to leave a comment . And the majority of users won't bother themselves with figuring out what went wrong , they will simply uninstall this extension . I think the devs of NoScript really should make it more simple-user friendly , add some templates for example , like light / mid / heavy privacy.
Even though I like your comment in general , I don't think Linux is a "user-friendly" system. And it's bloated with spying as well . Just install a fresh Linux and see the connections it's making right away .
