Mozilla announced the default full cookie protection (Full cookie protection) for all users Firefox on the desktop beyond private browsing and strict monitoring protection settings.

With Total Cookie Protection, Firefox is clearly winning an important point in its particular fight against the endless Chromium clones that lead Chrome and Edge (both proprietary). Marshall Erwin, head of security at Mozilla, said Firefox is now “The safest and most private of the largest browsers available for Windows and Mac” (Mozilla and its habit of neglecting Linux users who are most loyal to it).

Total Cookie Protection sounds great, but what is it really? Well, that’s a A feature designed to prevent cross-tracking of cookies by sites. To do this, it isolates the cookies used by the website in its own “jar”, thus preventing them from being tracked by other websites.. In this way, for example, Facebook is prevented from accessing cookies generated and stored after visiting Amazon. The following diagram, published by Mozilla, explains in a simple way how full cookie protection works.

In the picture you can see that before the implementation of Total Cookie Protection, all websites had access to all cookies generated and saved while browsing, but with protection enabled, websites only have access to their own cookies. thereby enhancing user privacy by clearly preventing their cross-tracking.

Mozilla explains it “This approach strikes a balance between removing the worst-case privacy features of third-party cookies, in particular the ability to track you, and allowing those cookies to fulfill their less intrusive use cases (such as providing accurate analytics).”.

It is important to note that the website as we know it would be much less practical and more difficult to manage without cookies, so the question is not whether they should exist or not, but how they are used. This protection, recently enabled by default in Firefox, opens the door, at least in theory, to force a more ethical use of cookies by reducing the scope for certain privacy practices that have become all too common.

Total cookie protection in Firefox for Linux.

Firefox’s situation has been critical for years. The Mozilla browser has slept too long to end up far surpassed not only by the ubiquitous Google Chrome, but more recently by the Microsoft Edge. The improvements he has made over the last few months are not helping him get back.

Total Cookie Protection, which is also enabled by default in Linux, is an important point for Firefox, however Given that the most widely used web browser is Google Chrome, we conclude that most users do not require privacy, but rather fluidity and quality when browsing.and this is where Mozilla’s product continues to falter against Chromium and its derivatives.
