If it is a page that the user has to use often this proves to be very useful. But cookies have evolved so much. Now it can not only remember the user’s preferences on a single website but could track him/her across the web.
Therefore, if you visit some page that has no connection with the original page, then also it can track your actions and learn your preferences. These are mainly used for ad targeting. To remove the cookies from tracking you Firefox has introduced a new update. The latest version has a new Strict Mode which claims to delete all browser history for any website. It also claims to delete cookies and supercookies.
Firefox clarifies that it is made possible by developing a “cookie jar” for every website that the user visits. This will sandbox each website and makes it impossible to share cookies and trackers between websites. Mozilla added, “That means you can easily recognize and remove all data a website has stored on your computer, without having to worry about leftover data from third parties embedded in that website.” The update is now live and make sure you gain from this added privacy feature.
