It would have been less alarming if the Firefox 128 release had shared more of that info. All I see is this: > Firefox now supports the experimental Privacy Preserving Attribution API, which provides an alternative to user tracking for ad attribution. This experiment is only enabled via origin trial and can be disabled in the new Website Advertising Preferences section in the Privacy and Security settings. Which (1) isn't clear if my installation is opted-in or out (what exactly does 'supports' mean? am I in the 'origin trial'?), (2) how to check or disable it--what/where are the configuration settings? Opaqueness doesn't go well with privacy-preserving. It gives a sense of bias which erodes trust.
