The advertiser’s don’t place the ads themselves. They say where and when they are placed, but the actual placing/integration is done by the likes of Google, Facebook, and, in this case, Mozilla.
That’s the “third party” that’s doing the tracking.

That’s not accurate. Mozilla isn’t placing the ads. Mozilla is storing impressions and then collating a privacy protecting report so that advertisers see that their ads are working, but not revealing information about the users to the advertisers. https://support.mozilla.org/en-US/kb/privacy-preserving-attribution
