Firefox扩展没有运行内容脚本

Question

I'm new to Firefox extension development, and am trying to port the Tab Stacker extension from Chrome. So far, I have these files:

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

chrome.mainfest:

content tabstacker  content/

install.rdf:

content/content.js:

var tabs = require('sdk/tabs');
var timeout = -1;
alert('loaded');

tabs.on('activate', function () {
    window.clearTimeout(timeout);
    alert('activate');
    if (!tabs.activeTab.isPinned)
        timeout = window.setTimeout(function () {
            tabs.activeTab.index = tabs.map(function (t) {
                return t.isPinned;
            }).reduce(function (acc, x) {
                return x ? acc + 1 : acc;
            }, 0);
        }, 1000);
});

The alert calls are for debugging (I'm not sure which console console.log logs to for an extension). But neither are shown, even after restarting the browser. The extension shows up in the add-ons manager. What am I doing wrong?

Looks like you're trying to use SDK modules without using the Add-Ons SDK, otherwise that tree would look quite different. Check out the Add-On SDK documentation and the Getting Started section:
