Get in control of your privacy automatically deleting the unused cookies created in each tab when you close it. This extensions deletes all the cookies created in a tab (which are not used by other tabs) when you close the tab. In this way your privacy is guaranteed. For example, as long as you stay on gMail, you are logged in, but once you close that tab (and all the others which are or have been on a Google site) the tracking cookies of Google disappear. Same for Facebook, once you close all the tabs which opened Facebook, its cookies disappear, so other sites cannot track you around the web. Clicking the little cookie-icon in the URL bar allows you to keep the cookies for the current site. Just in case you want to keep the ones of your blog or your email, for example.
