@arjen Hello, I was sent several copies of this github link overnight but haven't had a chance to read it yet. Can you clarify:
To your knowledge, what if anything is the difference between the "Ad measurement" feature listed in the "Ad Privacy"/"Ad Sandbox" pane of Google Chrome's settings, and the Firefox "Ad measurement" feature / the W3C standard to which you refer?
@mcc as far as I know, they refer to different approaches. I do not know all the details, but I think the Google approach is monopolistic, while the Mozilla/W3C attempts to keep something workable that is not confined to one ad network in control of the browser. But - not 100% sure. I am pretty sure that the Mozilla setting is not the same as what Chrome uses.
