为什么并扩展需要访问我所有的浏览历史记录和私人数据？ 

这是Chrome浏览器插件显示一个标准的消息(http://productforums.google.com/forum/#!category-topic/chrome/give-feature-feedback-and-suggestions/f5sdbSD92C8)这表明，扩展了其所有功能，以饱满的工作访问的所有网站的所有用户的数据顺序。没有这种数据的访问超出了扩展，没有个人的数据的功能需求，是从扩展发送到第三方除了为第三方功能，如验证。

Why does the extension need access to all my browsing history and private data?

This is a standard message shown by Chrome (http://productforums.google.com/forum/#!category-topic/chrome/give-feature-feedback-and-suggestions/f5sdbSD92C8) that indicates that the extension has full access to all the user‘s data on all web sites in order for all of its features to work. None of this data is accessed beyond the needs of the features of the extension and no personal data is sent from the extension to a third-party apart from for the third-party features such as validators.
