This feature will be implemented via loopback starting with version 127.0.0.1

/s 😂

It sounds like it will be really hard to differentiate bounce trackers from totally valid patterns like routing through federated identity servers 🤔 I wonder how they're dealing with that

We’re working on a new anti-tracking feature: Bounce Tracking Protection. It works similar to the existing Cookie Purging feature in Firefox, but instead of a tracker list it relies on heuristics to detect bounce trackers.

It’s based on the navigational-tracking-protections spec draft in the PrivacyCG[1]
