1637194 - Store first-party domain in CookieJarSetting

Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, task, P1)

Description

[Dimi Lee [:dimi]]

Currently dFPI doesn't work in Fission since storagePrincipal has a incorrect first-party domain.
It's because when we call StoragePrincipalHelper::ChooseOriginAttributes()[1] , it sets FPD through loadInfo's topLevelPrincipal, which is wrong in Fission because topLevelPrincipal is from the in-process top.

We are considering putting FPD in CookieJarSettings.

Attachment: Bug 1637194 - P2. Set firstPartyDomain to CookieJarSetting in nsHttpChannel::AsyncOpen

FirstPartyDomain is only set while loading a top-level document.
We added in nsHttpChannel::AsyncOpen to ensure that the value is updated
whenever we open a channel.

Attachment: Bug 1637194 - P4. Inherit the first-party domain from the parent document when creating CookieJarSetting in document

This fixes a issue that about:blank page can't get correct first-party
domain when fission is enabled.
