Does what it says it does, but as it says, it only works on YouTube. Since YouTube uses Flash by default (and you should unquestionably have Flashblock already installed), where it's really needed is on other sites that use html5 videos only, like theonion.com. Given how annoying autoplay videos are, it's hard to believe there isn't a more functional one out there already, but this seems like the only one?
