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.

This feature will be implemented via loopback starting with version 127.0.0.1
