Clodknocker's Web Snack is a free Firefox browser extension that shows you what your browser is doing behind your back. It finds the trackers, tells you what they are after, and shows you in a live view for every website you go to on Firefox. We don't snoop on you. The only time data leaves your device is if you want to enter an email address to be checked and then it only goes to Have I Been Pwned where it is checked.
