我们即将放弃这篇文档中描述的 Firefox 附加组件技术。
请勿使用下列技术开发新的附加组件。请改用 WebExtension 代替。
如果您在维护使用下列技术的附加组件，请考虑将其迁移为使用 WebExtensions 技术。
使用下列技术开发的附加组件可能不适用于多进程 Firefox（e10s），它已在 Firefox Nightly 和 Firefox Developer Edition 中默认启用，并很快将遍及 Firefox 的公测版（Beta）和正式版。我们准备了制作多进程兼容的附加组件的文档，但迁移到 WebExtension 是更加着眼于未来的选择。
有关的 wiki 页面写有协助开发人员过渡到新技术的有关资源、迁移路径、办公时间等信息。
This is a quick list of useful code snippets (small code samples) available for developers of extensions for the various Mozilla applications. Many of these samples can also be used in XULRunner applications, as well as in actual Mozilla code itself.
These examples demonstrate how to accomplish basic tasks that might not be immediately obvious.

- By default, the only possible standardized scripting language for HTML is ECMAScript. Hence, if you are going to use another scripting language you might expect that most of the browsers will not recognize it. Nevertheless, the increasing computational power of modern browsers together with the introduction of typed arrays in ECMAScript allow us, in theory, to build full virtual machines in pure ECMAScript. Therefore, it is also possible, in theory, to use ECMAScript for a smaller task: parsing exotic programming languages (i.e., creating compilers). This snippets shows a possible way to start from.
