In what conditions is privacy-preserving attribution used? PPA is enabled in Firefox starting in version 128. A small number of sites are going to test this and provide feedback to inform our standardization plans, and help us understand if this is likely to gain traction.

   - Firefox's "Privacy-preserving" ad tracking has other interesting issues. In another way the new ad snitching is worse than the old tracker cookies, Firefox doesn't *tell* you what data it's collected or reported, and unlike with cookies doesn't give you the ability to delete recorded "impressions".

   Also interestingly, the feature is not available to *all* advertisers currently, only a "small number" of partner sites. *Firefox doesn't disclose who they are*, again making this worse than $GOOG.
