Javascript Firefox扩展未运行内容脚本

我是Firefox扩展开发新手，正在尝试从Chrome移植扩展。到目前为止，我有以下文件：

$ tree
.
├── chrome.manifest
├── content
│   └── content.js
└── install.rdf

chrome.mainfest： install.rdf：

---

alert

调用用于调试（我不确定哪个控制台

console.log

logs用于扩展）。但即使在重新启动浏览器后，也不会显示这两个选项。扩展将显示在附加组件管理器中。我做错了什么？

看起来您正在尝试使用SDK模块而不使用附加组件SDK，否则该树将看起来完全不同。查看附加SDK文档和入门部分：

谢谢。我一直在跟踪，这似乎是从FF 1.5天开始的。
