73 diffs ( 33 new, 19 gone, 21 different )

new in v131.0:

• pref("network.http.microsoft-entra-sso.enabled", false); - 1768724 - https://github.com/arkenfox/user.js/pull/1892/commits/5c77848ba6c1e791f394f25e0de901c4b02e009f
• pref("privacy.bounceTrackingProtection.mode", 3); - 1894040 - https://github.com/arkenfox/user.js/pull/1892/commits/8c5ab42fc86194e5a4eab3ba95f4cf3235cd1559
  • we will get this with ETP Strict in FF133 when it's ready to land
  • also see my comment below

pref("geo.prompt.open_system_prefs", true);
pref("network.http.network_error_logging.enabled", false);
pref("permissions.media.query.enabled", false);
pref("permissions.media.show_always_ask.enabled", false);

changed in v131.0:

FYI

• pref("identity.fxaccounts.telemetry.clientAssociationPing.enabled", true); // prev: false
  • 1889123 Measure potential device migrations for Mozilla Account holders
  • requires a FF account and if you have one, then this is not an issue
• pref("network.cookie.sameSite.noneRequiresSecure", true); // prev: false 1909673
  • about time, sounds good to me
  • https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie

  • None Means that the browser sends the cookie with both cross-site and same-site requests. The Secure attribute must also be set when setting this value, like so SameSite=None; Secure. If Secure is missing an error will be logged:

  • also see the below re CHIPS

  • Warning: Cookies with the SameSite=None; Secure that do not also have the Partitioned attribute may be blocked in cross-site contexts on future browser versions. This behavior protects user data from cross-site tracking.

• Cookies Having Independent Partitioned State (CHIPS) + 1865198 META
  • pref("network.cookie.CHIPS.enabled", true); // prev: false
  • pref("network.cookie.chips.partitionLimitEnabled", true); // prev: false
  • sounds good to me - "cookies" are double-keyed by the origin that sets them and the origin of the top-level page
  • AFAICT this is also a precursor to Firefox blocking all third party cookies by default (but allowing CHIPS)
