Hm, good points. I’d add: If you open a new tab in firefox, there’s google’s search engine pinned, so you can see (and use) that trade-based service easily. Plus they support this function of @google in their tab to make an easy search via google. Because of all these points I’d put them into the category rejected. Promotions (trades) are a slippery slope, because once you do them, you depend on them. And sooner or later google might say to firefox: I give you some more money if you give me some data of your users…

Incendia in omnibus tabs https://getpocket.com/premium suum mercaturae fundatum servitium promovet. Etiam file communicantes operas suas promovent quae optiones premium (solvit) praebent. Horum igitur intellege.

5 sic 4 ex caudices adsentior. Ut latus notae ex illo optare potes: in Privacy & Securitatis panel ->

Librum ad Firefox Data Collection et sectionem utere et notam cistas ubi dicit "Permitte Firefox mittere technicam et commercium notitias Mozillae"

Firefox aliquas notitias colligit sed maxime ad technicas causas https://www.mozilla.org/en-US/privacy/faq/ – sic nonnullas notitias illis trade.
