Take back your privacy
Firefox is rolling out Total Cookie Protection by default to more Firefox users worldwide, making Firefox the most private and secure major browser available across Windows, Mac, Linux and Android.
What is Total Cookie Protection?
Total Cookie Protection works by creating a separate “cookie jar” for each website you visit. Instead of allowing trackers to link up your behavior on multiple sites, they just get to see behavior on individual 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.
What? I thought they already did this three years ago. How do I tell if I've got it already turned on? I seem to remember setting some kind of config flag but it doesn't seem easy to spot which one it was.
Edit: Oh, this is from 2022. What's changed since then seems unclear.
