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…

Firefox 还可以通过付费来决定使用哪个默认搜索引擎。这是直接贸易。他们想要你百分百的关注。我很难给 Firefox 贴上自由交易的标签… https://www.investopedia.com/articles/investing/041315/how-mozilla-firefox-and-google-chrome-make-money.asp

Firefox 在所有选项卡上推广其基于贸易的服务 Pocket https://getpocket.com/premium。他们还推广提供优质（付费）选项的文件共享服务。所以要注意这些。

我同意这一点，所以 5 块中有 4 块。作为旁注，您可以选择退出：在“隐私和安全”面板中 ->

Scroll down to the Firefox Data Collection and Use section and uncheck the boxes where it says “Allow Firefox to send technical and interaction data to Mozilla”

Firefox 确实收集了一些数据，但主要是出于技术目的 https://www.mozilla.org/en-US/privacy/faq/ – 因此您可以向它们交换一些数据。
