1683165 - Add a pref that allows users to disable all automated anti-tracking webcompat heuristics and skiplists

Status: RESOLVED FIXED

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

Description

[Steven Englehardt [:englehardt]]

We often face a tradeoff between uncompromising privacy features and web compatibility. To get sites working under stricter defaults, we've landed on the general approach of trying to detect the user's intent and automatically relaxing protections when we think the user is trying to achieve something that tracking protection would otherwise break.

This is great for most users, but there are certainly powerusers that would prefer Firefox to never unblock tracking without their explicit approval. It would be great to give these users a checkbox

Here are examples:

• The cookie blocking heuristics
• The 5 automatic grants when requestStorageAccess is called.
• dFPI's automatic grants (not documented yet)
• Content blocking script shimming's automatic relaxation of Facebook script blocking when a user interacts with a Facebook login button

Ideally all of these get tied to a single pref that's then controlled by a checkbox in the Custom mode of ETP. The checkbox should be default-on.

For the storage access API we also have dom.storage_access.auto_grants and dom.storage_access.max_concurrent_auto_grants which can help.
