Yes. It's possible, but some of the functionality provided by these libraries are available through XPCOM, XUL, and JavaScript. In addition, authors should take care if libraries modify primitive object prototypes (String.prototype, Date.prototype, etc.) and/or define global functions (eg. the $ function). These are prone to cause conflict with other add-ons, in particular if different add-ons use different versions of libraries and so on. Developers need to be very, very careful with using them. Mozilla does not offer documentation on using them to build add-ons.
可以，但这些库的某些功能需要通过 XPCOM、XUL 和 JavaScript 来实现。此外，作者应该注意这些库是否会修改对象的原始 prototype（String.prototype、Date.prototype 等）和/或定义全局变量（例如 $ 函数）。这些可能会与其他附加组件相冲突，特别是如果另一个附加组件使用了另一个版本的库时。开发者使用它们时需要非常小心，Mozilla 不提供使用它们来制作附加组件的文档。
