The second is what we call “interaction data.” This is data about an individual’s engagement with { -brand-name-firefox }, such as the number of tabs that were open, the status of user preferences, or number of times certain browser features were used, such as screenshots or containers. For example, we collect this data in terms of the back button, that arrow in the upper left corner of your browser that lets you navigate back to a previous webpage in a way that shows us someone used the back button, but doesn’t tell what specific webpages are accessed.
第二类是我们所说的“交互数据”。这是关于个人与 { -brand-name-firefox } 的交互情况的数据，例如打开的标签页数量，用户偏好设置状态或某些浏览器功能的使用次数，如屏幕截图或身份标签页。 例如，就我们收集后退按钮的数据而言（即浏览器左上角可让您回到之前浏览的网页的箭头），我们可以以某种形式看到有人点击了后退按钮，但不会知道用户访问了哪些特定网页。
