I've actually taken to using a Javascript toggle extension that defaults to off. Makes the web a far better experience when it comes to venturing into unfamiliar territory (going to a site you haven't been to in a while, if it all, or following some shortened url that leads who knows where, or just clicking through something on a news aggregator for example). And if it breaks the website? 9 times out of 10 that's your "It's not worth it" signal to just close the tab and move on. If they can't even deprecate gracefully, they almost never use javascript competently and unobtrusively.
