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…
