如何同步 FF simple-prefs

Question

我想使用 require('sdk/preferences/service') 同步我的 Firefox 插件的设置。

这是我的非工作试用版： package.json:

    {
    "title": "Test",
    "name": "test",
    "author": "devname",
    "version": "1.0.0",
    "main": "lib/main.js",
    "engines": {"firefox": ">=38.0a1","fennec": ">=38.0a1"},
    "license": "MPL-2.0",
    "id": "test@devname.org",
    "permissions": {"private-browsing": true},
    "dependencies": ["addon-kit"],
    "preferences": [{
            "title": "Color 1",
            "type": "color",
            "value": "#000000",
            "name": "1"
    }]}

lib/main.js:

    const
        addonid = require('sdk/self').id,
        simprefs = require('sdk/simple-prefs'),
        simstore = require('sdk/simple-storage'),
        service = require('sdk/preferences/service'),
        store = simstore.storage
    ;

    service.set('services.sync.prefs.sync.extensions.' + addonid + '.syncy', true);

    simprefs.on('1', function() {
        simprefs.prefs["syncy"] = simprefs.prefs["1"];
    });
})();

因此，当我在 Addon-Manager 中将 pref 1 设置为颜色 #777777 时，pref syncy 将获得相同的值（在 about:config 页面上可见）。
当我使用 2 个 Firefox 配置文件并向 Mozilla 注册以进行同步并在每个配置文件上安装此附加组件时，我希望在一个配置文件上更改此值会在另一个配置文件上更改它（因此 about:config 上的设置 -> extensions.test@devname.org.syncy) - 但事实并非如此。
我做错了什么？

Answer 1

来自 Mozilla Wiki 关于在配置文件之间同步加载项的条件：

Currently, Sync will synchronize add-ons that meet the following criteria:
- Is an extension or theme (i.e. not a plugin)
- Is installed in the profile directory
- Is installed explicitly by the user inside of Firefox
- Is installed from a trusted URI

我认为问题在第四个条件。在开发期间，Firefox 不能信任您的插件。但在同一篇文章中，暗示了绕过第 4 个条件的可能变体：

Why is Functionality Limited to Add-ons from addons.mozilla.org?
First, this is only the default behavior. The services.sync.addons.trustedSourceHostnames preference is a comma-delimited list to allow other trusted hostnames.
