Firefox Desktop has fixed its Blob leak, the browser is passing all of https://PrivacyTests.org State Partitioning (cross-site data leak) tests! And this fix has propagated to LibreWolf as well
Firefox and LibreWolf join Brave, Mullvad, and Tor Browser in having no leaks of data between websites. Firefox's Gecko browser engine thus becomes the first of the three major browser engines (Gecko, WebKit, Chromium) to have a clean bill of health on cross-site data leaks on desktop.
@ecksmc Ive been a firefox user for over a decade. It's my go to browser and it gives me joy to see it further improve.
I worry very much about how much chrome is out there. Monocultures are bad in nature and they are bad on the net. That's a single point of failure for a lot of folks.
