Starting with Firefox 127, we're enabling a new anti-tracking feature in Nightly: Bounce Tracking Protection.
This detects bounce trackers based on redirect behavior and periodically purges their cookies & site data to prevent tracking.

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]
