Containers let you create profiles in Firefox for all of your online lives. Custom labels and color-coded tabs help keep different activities — like online shopping, travel planning, or checking work email — separate. Because Containers store cookies separately, you can log into the same site with a different account in each Container, and online trackers can’t connect your browsing in one container to another. So you can keep your shopping self separate from your social self from your work self, without worrying about being followed around the Web.
容器（身份）使您可以在 Firefox 中为不同的在线生活创建不同的领地。自定义的标签和颜色更可区分它们。领域例如：在线购物、旅行计划、检查工作邮件等——将它们分离开来。因为容器将独立存储 Cookie，因此您可以在各个容器中用不同的账户登录同一个网站。在线跟踪器也将无法将您在不同容器间的浏览关联，从而不必再担心网络将您的购物、工作与生活关联与混淆。
