1831265 - The fingerprinting randomization key doesn't properly inherit to a javascript: URL document

Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, defect)

Description

[Tim Huang[:timhuang]]

See Document::CookieJarSettings(), we don't propagate the random key in the case where we need to create a cookieJarSettings from the parent document. This will end up with that the javascript URL document won't have a random key so the fingerprinting randomization won't work there.

Attachment: Bug 1831265 - Inherit fingerprinting random key from the parent document when creating cookieJarSettings in a document. r?pbz!

There are some cases that we need to create cookieJarSettings from the
parent document, such as Javascript URL document. We need to inherit the
random key from the parent document to properly propagate the key to the
javascript URL document.

This patch implements the inheritance of the random key and add a test
for it.
