1610455 - Record content blocking log when a window is in-process

Status: NEW

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

Description

[Dimi Lee [:dimi]]

Right now, when WindowGlobalParent is created in-process, we don't record content blocking log because we thought there shouldn't be such a case[link].

In Bug 1609144, we found out there were cases tracker are loaded in in-process windows. For example:

1. Developer tools -> Network Panel -> Click on a request with trackers -> Response
2. View Page Info -> Media
   There might be the other cases.

This bug is to discuss if we should record content blocking log when it is in-process.

I think we can just throw the data away in those cases, personally.

Can you please explain in more detail what causes us to hit that code path in those two examples? I'm not sure if I understand...

I think Johann is probably right about those use cases, but I'd like to make sure we aren't also ignoring something else that would matter in practice.
