JShelter is a browser extension to give back control over what your browser is doing. A JavaScript-enabled web page can access much of the browser's functionality, with little control over this process available to the user: malicious websites can uniquely identify you through fingerprinting and use other tactics for tracking your activity. JShelter aims to improve the privacy and security of your web browsing. For more details, see JShelter threat model.
A handy feature, which I personally like very much, is that JShelter blocks all requests from website to localhost.
