As of Firefox 133 I intend to turn on Bounce Tracking Protection for users in ETP “strict” mode on desktop. It has been developed behind the `privacy.bounceTrackingProtection.mode` preference. The feature has been enabled in Firefox Nightly since version 127.

Other browsers:

Bug to turn on in ETP “strict”: Bug 1907390 - Add BounceTrackingProtection prefs to ETP Strict configuration

Standard: Work item in the PrivacyCG: https://privacycg.github.io/nav-tracking-mitigations/#bounce-tracking-mitigations

Mozilla standards position: https://mozilla.github.io/standards-positions/#bounce-tracking-mitigations

TAG review: https://github.com/w3ctag/design-reviews/issues/862

This feature was previously discussed in this "Intent to prototype" thread: https://groups.google.com/a/mozilla.org/g/dev-platform/c/M6erM0SjPTM/m/khVI7lm_AAAJ

Have there been any interesting (or not, I guess) bug reports since this was enabled in Nightly?

Hi Mike!

We have not received any bug reports concerning website breakage for BTP in Nightly yet. We will track them here as they come up: Bug 1895504 - [meta] Bounce Tracking Protection Website Breakage. Now that the feature is in Firefox Beta it will be exposed to a larger user population.

Directly attributing reports of missing data / broken websites to the feature is tricky. We do log warnings to the DevTools when we detect a bounce tracker. We're also working on logging tracker purge actions in the local profile so we can work with bug reporters to identify BTP breakage after the fact.

Best Regards,
Paul

Excellent - thanks for the pointer to the meta bug. :)

Good luck!
