Steps to reproduce:

starting in FF81, network.cookie.cookieBehavior = 1 (= block all 3rd-party cookies/site data) incorrectly blocks 1st party storage access in file:/// URIs.

STR:

  • set network.cookie.cookieBehavior to 1
  • save the following demo code as an HTML file and open it as a file:/// URI
<!DOCTYPE HTML>
<html>
<body>
  <script>
    try {
      document.body.innerText = 'typeof window.indexedDB: ' + typeof window.indexedDB;
    } catch (e) {
      if (e instanceof DOMException) document.body.innerText = 'DOMException: ' + e.message + ' (' + e.name + ')';
    }
  </script>
</body>
</html>

Actual results:

DOMException and a console message:

Request to access cookie or storage on “file:///.../test.htm” was blocked because we are blocking all third-party storage access requests and content blocking is enabled.

Expected results:

1st party storage access shouldn't be blocked.

Thanks for the detailed report, this a duplicate of bug 1663192.
