title: How to revoke given permission in Chrome and Firefox?
body: <p>One of the new APIs made available to developers is <a href="http://www.thoughtresults.com/geolocation-api" rel="noreferrer">Geolocation API</a>. As it's been defined in Specification, any browser should take the express permission of the user when revealing his/her geographic position to the surfed website. However, it's also been said that user can revoke that given permission at any time. I searched almost everywhere in Chrome and Firefox and I didn't find any place to revoke given permissions. Does anyone know how should I do that? (This is also the case in <a href="http://www.thoughtresults.com/contacts-api" rel="noreferrer">Contacts API</a>)</p>
