动态关于：使用JavaScript代码模块的URL（XPCOMUtils.jsm）？

我正在尝试动态注册Firefox扩展的自定义URL，相对于一个变量。

例如：

- If var = 1, then create... about:123

- If var = 2, then create... about:abc

- If var = 3, then create... about:xxx

JavaScript代码模块是向我建议的，特别是XPCOMUtils.jsm，但是如何在代码中实现它呢

我浏览了这些页面，但毫无结果：

我已经使用

chrome.manifest

文件实现了一个定制的staticabout:URL。但是我不需要关于：URL的静态。我需要动态关于：URL，相对于Firefox扩展内部的变量

谢谢你的帮助

我写道，这将允许您动态地向firefox添加/删除关于：什么的URI

这是以下各项的当前源代码：
