1506947 - Add a pref for site-specific workarounds for blocking cookies from trackers

Status: RESOLVED FIXED

(Firefox :: Protections UI, enhancement, P2)

Description

[(no longer active)]

We need to add a site-specific workaround pref in order to allow whitelisting specific domains and URLs from being subject to third-party cookie blocking from trackers only.

This could be useful for issues such as excessive challenges users get from recaptchas, as well as unexpected and unpredictable breakage that we discover in the wild after shipping.

This can use some of the code added in bug 1505212...

How is this related to bug 1450398?

While the title of that is specific to Web Extensions, the correct patch for that bug will enable Resist Fingerprinting to be selectively applied or un-applied to individual origins (as well as exempting the system principal and web extensions.)

I don't imagine that the patch for this bug would overlap with this (since the tracking work isn't making use of any of RFP); but the goal of site-specific exemptions made want to link them; since if/when we ever get to 1450398, the method we use for the exemptions will probably mimic this one.

I doubt it...  This fix would probably happen somewhere inside nsChannelClassifier::CheckIsTrackerWithLocalTable().

I have a patch here which fixes the Google Recaptcha challenge issue...  Need to write a test for it.
