Mozilla’s system only measures the success rate of ads—it doesn’t help companies target those ads—and it’s less susceptible to abuse, EFF’s Lena Cohen told @FastCompany@flipboard.com. “It’s much more privacy-preserving than Google’s version of the same feature.”

Privacy experts say the new toggle is mostly harmless, but Firefox users saw it as a betrayal.
“They made this technology for advertisers, specifically,” says Jonah Aragon, founder of the Privacy Guides website. “There’s no direct benefit to the user in creating this. It’s software that only serves a party other than the user.”
From what I’ve seen PPA doesn’t depend on OHTTP to do the obscuring. This page mentioned Distributed Aggregation Protocol and differential privacy, that are meant to ensure that it is literally impossible for any one party to see your data. Not just “obscured”, but impossible to access.
But be sure to let us know what data about us a partner could theoretically view, and how, if you disagree.

Clearly not impossible even according to the standards authors.
I see only two data leak risks mentioned:
The first doesn’t need PPA. As for the second, Firefox can already conspire to compromise your privacy, if you’re using it.
I’m still looking for some concise documentation about exactly what Firefox sends, and if I could, I would love to intercept that data so that I can send it myself at a later time, with extra details
There’s a bit in the technical explainer here. But there’s really no way for you to add details; the whole point is to share nothing about you specifically.
