Firefox is experimenting with a new third-party cookie policy. Alex Fowler, Mozilla’s Lead on Privacy and Public Policy, puts it this way:
On Friday, Mozilla released a Firefox patch into its “Nightly” channel that changes how cookies from third party companies function. Users of this build of Firefox must directly interact with a site or company for a cookie to be installed on their machine.
Firefox is exploring this change because we believe it’s good for the Web. We did not test other Mozilla web sites first, because we do not play favorites. For example we didn’t know for sure, when the change was applied to Firefox Nightly, whether Persona would continue to function as expected. We believe this Firefox cookie policy change is good for users, and all of our products should live by the rule we’re proposing.
Of course, since Persona is built to respect user privacy, we don’t set a cookie unless you directly interact with Persona. So it is without much surprise that our first tests indicate that Persona works just fine with Firefox’s new third-party cookie policy.
Persona will always strive to provide the easiest login solution for users and developers, all the while protecting user privacy. It’s good to see that our approach meets the criteria set by Mozilla’s very best privacy minds.
