Total Cookie Protection Now a Default Option in Firefox

The move makes Firefox the most private and secure major browser available across Windows, Mac and Linux.

Firefox cookie protection

Mozilla announced that Total Cookie Protection is now a default feature for all Firefox users worldwide, making it the most private and secure major browser available across Windows, Mac and Linux. Total Cookie Protection confines cookies to the site where they were created, thus preventing tracking companies and giants like Google and Facebook from using these cookies to track your browsing from site to site.

Whether it’s applying for a student loan, seeking advice through a health site, or browsing an online dating app — massive amounts of our personal information is online and this data is leaking all over the web. The super-personalized ads you often see online are made possible by cookies that are used to track your behavior across sites and build an extremely sophisticated profile of who you are.

These profiles are then used by major ad companies, like the mentioned Google and Facebook, or are sold to interested third parties. And you would be surprised just how many of those third parties are in the business these days.

The possibility that your every move online is being watched, tracked and shared is an alarming reality, according to Mozilla and we tend to agree with that statement. That was the reason why they have developed Total Cookie Protection.

Total Cookie Protection 101

Total Cookie Protection works by creating a separate “cookie jar” for each website you visit, effectively preventing trackers from seeing your behavior across multiple sites.

Any time a website or third-party content embedded in a website deposits a cookie in your browser – that cookie will be confined to the cookie jar assigned to only that website. Other websites won’t be able to reach into the cookie jars that don’t belong to them and find out what the other websites’ cookies know about you — giving you freedom from invasive ads and reducing the amount of information companies gather about you.

Total Cookie Protection

This approach, according to Mozilla, strikes the balance between eliminating the worst privacy properties of third-party cookies (the tracking part) and allowing those cookies to fulfill their less invasive use cases such as providing analytics. With Total Cookie Protection in Firefox, people can enjoy better privacy without sacrificing the browsing experience.

Total Cookie Protection builds on top of Firefox’s earlier Enhanced Tracking Protection (ETP) feature, which works by blocking trackers based on a maintained list. If a tracker for some reason isn’t on that list, it can still track users and violate their privacy. And if an attacker wants to thwart ETP, they can set up a new tracking domain that isn’t on the list. Total Cookie Protection avoids these problems by restricting the functionality of all cookies, not just those on a defined list.

Years in the making…

Mozilla first began to block tracking in 2015 with the release of Tracking Protection, a feature users could turn on by going into the Private Browsing mode.

Three years later, Enhanced Tracking Protection was introduced and turned on by default for all Firefox users in 2019.

The release of Total Cookie Protection is the result of experimentation and feature testing, first in ETP Strict Mode and Private Browsing windows, then in Firefox Focus earlier this year. Now, it is the default feature for all Firefox desktop users worldwide.

And yes, we advise you to use Firefox instead of Google’s Chrome or Microsoft’s Edge browsers. Even better, pair it with a good VPN for total privacy protection. 😉
