1679512 - Stop computing the ContentBlockingAllowListPrincipal for sub-documents

Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, enhancement, P3)

Description

[Tim Huang[:timhuang]]

We compute the ContentBlockingAllowListPrincipal in the content document. We compute it for every document, but actually it is not necessary. We only use the ContentBlockingAllowListPrincipal of the top-level document. So, we can stop computing the principal for sub-documents.

We only use the contentBlockingAllowListPrincipal for excluding sites from content
blocking for top level documents. We don't need it in the content process and should
not compute it for every document.
