JShelter focuses on fingerprinting prevention, limitations of rich Web APIs, prevention of attacks connected to timing, and learning information about the computer, the browser, the user, and surrounding physical environment and location. JShelter provides a fingerprinting report and other feedback that can be used by future security research. Thousands of users around the world use the extension every day.
