Another Firefox W
I’m surprised this isn’t already a thing for decades but ok.
It is already a thing for 2 years, since this is just an update to an old blog post to say that they’ll do even more now.
Aside from that, it wasn’t a thing, because as per the usual something on the web breaks when you change behavior like that, because some webpages rely on third-party cookies to provide their core functionality.
Someone (in this case the Tor Browser devs) had to come up with a way to have third-party cookies
and eat them, toobut isolate them from the third-party cookies that got created on other webpages.
On the technical side, this is called “first-party isolation”, and basically each domain you browse to gets its own cookie jar to store first- and third-party cookies in.
Still waiting for it on mobile
It’s there on mobile. Check the details tab in tracking protection. You should see it mentioned there.
Well shit! How long has that been there? I still use Firefox (ok, Librewolf and Mull) but I had given up on ever seeing that on mobile.
It’s been here since more than a year. https://blog.mozilla.org/en/mozilla/firefox-androids-new-privacy-feature-total-cookie-protection-stops-companies-from-keeping-tabs-on-your-moves/
