Mozilla is rolling out today Total Cookie Protection by default for all Firefox users across the world. The new feature will complement Firefox’s existing privacy protections by creating a separate “cookie jar” that will confine cookies to the site where they were created, preventing trackers to analyze user behavior across multiple sites.
“Any time a website, or third-party content embedded in a website, deposits a cookie in your browser, that cookie is confined to the cookie jar assigned to only that website. No other websites can 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,” the company explained.
This new Total Cookie Protection complements Firefox’s existing Enhanced Tracking Protection feature, which is turned on by default to block trackers from a list maintained by Mozilla. However, that feature alone wasn’t enough to prevent cross-site tracking as trackers who aren’t on the list can still track users without their knowledge. “Total Cookie Protection avoids these problems by restricting the functionality for all cookies, not just for those on a defined list,” Mozilla emphasized.
Thanks to Total Cookie Protection now being enabled by default, Mozilla claims that Firefox is now “the most private and secure major browser available across Windows and Mac.” If you’ve ever been surprised by how relevant and specific some ads you may encounter while browsing the web can be, then Firefox is definitely a great option. In contrast, Google is also committed to phasing out support for third-party cookies in Chrome with its new Privacy Sandbox, though the company has now delayed these plans to 2023.
