All Firefox users on desktop will now be protected by the browser's Total Cookie Protection feature by default. Mozilla calls it the browser's "strongest privacy protection to date," because it confines cookies to the site where they were created. That means it keeps cookies isolated, preventing tracking companies from being able to access them to monitor your activity without your consent. Without the feature, websites can "reach into the cookie jars that don't belong to them," as Mozilla puts it. That gives them more information about you in order to serve you specific ads based on your activity.
