来自 bootstrap CDN 的错误和未知 类

Question

我在开发人员控制台中收到很多错误，但它们都被列为来自 maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css

下面列出了一些错误：

Unknown pseudo-class or pseudo-element '-webkit-inner-spin-button'.  Ruleset ignored due to bad selector.
Unknown pseudo-class or pseudo-element '-webkit-search-cancel-button'.  Ruleset ignored due to bad selector.
Expected end of value but found ' '.  Error in parsing value for 'width'.  Declaration dropped. 
Expected end of value but found ' '.  Error in parsing value for 'margin-top'.  Declaration dropped. 
Unknown pseudo-class or pseudo-element '-ms-input-placeholder'.  Ruleset ignored due to bad selector. 
Unknown pseudo-class or pseudo-element '-webkit-input-placeholder'.  Ruleset ignored due to bad selector.
Expected end of value but found '�'.  Error in parsing value for 'line-height'.  Declaration dropped.
Unknown property 'user-select'.  Declaration dropped.

这是一个针对潜在雇主的个人网站，所以我不想让他们认为我的网站有错误。有谁知道我为什么会得到这些以及如何摆脱它们？

好像是Firefox的问题？在 Chrome 中加载带有 link 到 bootstrap.min.css 的空白 html 文档并不表示控制台面板中有任何错误；在 Firefox 中你会遇到一堆错误。
