Mozilla has its Total Cookie Protection feature enabled by default on all Firefox users. This makes it more difficult for websites and advertisers to track the behavior of Firefox users.
Previously, Total Cookie Protection was only available if the user had activated the ‘strict’ browser privacy setting. Now it is also with the default privacy setting, writes Mozilla† According to the company, this will protect the user’s privacy “even better”.
Total Cookie Protection has been part of Enhanced Tracking Protection since Firefox 86. Any tracking cookie that tracks users across multiple websites is siled by Total Cookie Protection. As a result, the cookies can no longer be shared with other websites.
Enhanced Tracking Protection uses a list of tracker blocker Disconnect to recognize and block trackers. However, it only works well if that list from Disconnect is up to date. Users can still track domains that are not on the list. Total Cookie Protection works in a different way. It uses State Partitioninga technology that identifies whether a third-party cookie is trying to track someone across websites.
