Firefox’s Total Cookie Protection Aims To Stop Tracking Between Multiple Sites

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. From a report: The “Total Cookie Protection” feature is included in the web browser’s latest release — alongside multiple picture-in-picture views — 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.” 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.
