下面列举用来打包Xpcom或者NpAPI Plugins的使用的文件列表（未全部列举出来），详情见：
https://developer.mozilla.org/en/Bundles
| 包的根目录 | 描述 | 版本信息 |
| /install.rdf | 其文件是一个xml文件，里面有插件的名称，作者，版本，与firefox的版本兼容等信息 | Gecko 1.9（Firefox3.6）之后都支持 |
| /chrome.manifest | 用来描述各个文件的存放路径，以及程序的一些界面的描述等 | >= Gecko 1.8 |
| /components/* | XPCOM components (*.js, *.dll), and interface files from *.xpt | >= Gecko 1.7 |
| /plugins/* | 用来存放NPAPI插件(*.dll,*.so …)Gecko2.0（Firefox 4）和之前版本有些差别，在下面说明 | >= Gecko 1.8 |
| /platform/* | 用来存放各个平台（windows，linux，mac）下的xpcom动态库，需要分目录存放，目录的名称使用平台+编译器定义，具体内容见官方文档 | >= Gecko 1.8 |
打包XPCOM
包的结构如下：
FTXpCom
│ chrome.manifest
│ install.rdf
│
├─components
│ IGetTokenInfo.xpt
│ ISlotManager.xpt
│
└─platform
├─Darwin_x86-gcc3
│ └─components
│ FtXpCom.dylib
│
├─Linux_x86-gcc3
│ └─components
│ FtXpCom.so
│
└─WINNT_x86-msvc
└─components
FtXpCom.dll
## Reference for Chrome Registration: https://developer.mozilla.org/en/Chrome_Registration
# XPT Files:
# The path of any XPT files must be listed explicitly
interfaces components/IGetTokenInfo.xpt
interfaces components/ISlotManager.xpt
# Binary Components
# Binary components must be listed explicitly in a manifest using a binary-component directive:
# Platform-Specific Directories

打包NPAPI
相对XPCOM而言，制作一个NPAPI插件包很简单。只需要一个配置文（install.rdf)和一个plugins目录（里面放的都是各个平台的NPAPI动态库）。不用Chrome.manifest也可以。
包结构：
Gecko 2(Firefox 4) and later:
FtNpRuntimeCom
│ install.rdf
│
└─plugins
npruntime.dll
npruntime.so
npruntime.dylib
Gecko 1.9.2 (Firefox 3.6) and earlier
FtNpRuntimeCom
│ install.rdf
│
└─platform
├─Darwin_x86-gcc3
│ └─plugins
│ npruntime.dylib
│
├─Linux_x86-gcc3
│ └─plugins
│ npruntime.so
│
└─WINNT_x86-msvc
└─plugins
npruntime.dll
