As part of its war on web tracking, Mozilla is adding a new tool to Firefox aimed at stopping cookies from keeping tabs on you across multiple sites. The "Total Cookie Protection" feature is included in the web browser's latest release — alongside multiple picture-in-picture views (more on that below) — and essentially works by keeping cookies isolated between each site you visit. Or, in Mozilla's words: "By creating a separate cookie jar for every website."

Google is also working on a plan to kill off third-party cookie tracking on its Chrome web browser as part of its Privacy Sandbox project, an initiative that seeks to allow personalized ads while limiting individually identifying data.

Firefox's new feature pares with last month's network partitioning tool, which works by splitting the Firefox browser cache on a per-website basis to prevent tracking across the web, itself targeted at blocking more stubborn "supercookies." According to Mozilla, these types of cookies are more difficult to delete and block as they are stored in obscure parts of the browser, including in Flash storage, ETags, and HSTS flags. Both tools are available as part of Firefox's enhanced tracking protection suite in "strict mode" on desktop and Android.

It is not very easy to spot by untrained eye - but this is part of total control and censorship war. Plus hundreds of billions of more income for big guys who control all major browsers.

Let me explain - now small and medium sites get only around 10-35% of income from ads (mostly thanks for Google) and this number constantly drops, especially for small guys. Hence we see more and more unnecessary ads.

Most income comes from referrals and selling personal data and tracking data.

Tech giants want to cut large part of this income and such way force small and medium guys to place even more ads. In same time all sites that will considered unnecessary will be silently killed by lower ranking (as Google do with forums now) and by simple economic reasons.

GDPR also hit smallest sites most - as they have worst aka default large popups, they also needed to spend time on doing this shit. But large sites are quite happy with it as it did not change anything for them - instead it made it look nice and legal.
