'Firefox's Total Cookie Protection is a sophisticated set of privacy improvements that enforce a simple, revolutionary principle: your browser should not allow the sharing of cookies between websites,' said Arthur Edelstein, Firefox Privacy and Security Senior Product Manager at Mozilla.
Total Cookie Protection is designed to force all websites to keep their cookies in separate 'jars,' thus preventing them from tracking you across the web and building browsing profiles.įirst introduced in Firefox 86 in February 2021, this privacy feature was only active until now when users would manually toggle on ETP Strict Mode in the web browser's settings.
This is because, starting with the Firefox 89 version released today, Total Cookie Protection will be enabled by default in Private Browsing windows. Mozilla says that Firefox users will be protected against cross-site tracking automatically while browsing the Internet in Private Browsing mode.
