Firefox插件开发，如何更改about:config设置 [英] Firefox addon development, how to change about:config setting

问题描述

我正在尝试开发一个简单的插件，该插件在新选项卡中打开一个不同于firefox默认页面的网页.我想在about:config中更改两个默认设置值，但似乎无法通过当前配置来实现.

Hi I'm trying to develop a simple addon which opens a web page different from firefox default page in new tab. I want to change two of the default settings values in about:config, but it seems I cannot achieve this through my current configuration.

我正在使用firefox推荐的插件SDK来开发插件.(

I'm using the Add-On SDK recommended by firefox to develop the add-on.(creating a simple add-on using the SDK

通过查看about:config设置，我发现如果将"browser.newtab.url"设置为网页URL，并将"moa.ntab.openInNewTab"从true设置为false，则可以实现此功能.因此，我按照上面的教程进行操作，并添加了./defaults/preferences/pref.js来更改配置.

By looking into the about:config setting, I found that if I set "browser.newtab.url" to the web page url, and "moa.ntab.openInNewTab" from true to false, I can realize such function. So I followed the tutorial above and added ./defaults/preferences/pref.js for changing the config.

我当前的目录如下:

ff-addon
  └─ data
  └─ defaults
     └─ preferences
        └─pref.js
  └─ lib
     └─ main.js
  └─ package.json
  └─ test
     └─ test-main.js

/defaults/preferences目录中的pref.js代码如下:

the pref.js code in the /defaults/preferences directory is as follows:

pref("browser.newtab.url", "http://www.baidu.com");
pref("moa.ntab.openInNewTab", false);

我没有更改main.js中的代码.其代码如下所示:

I did not change the code in main.js. Code of it is shown below:

var buttons = require('sdk/ui/button/action');
var tabs = require("sdk/tabs");

var button = buttons.ActionButton({
  id: "mozilla-link",
  label: "Visit Mozilla",
  icon: {
    "16": "./icon-16.png",
    "32": "./icon-32.png",
    "64": "./icon-64.png"
  },
  onClick: handleClick
});

function handleClick(state) {
  tabs.open("http://www.mozilla.org/");
}

我也没有更改package.json中的代码:

I did not change the code in package.json either:

{
  "name": "ff-addon",
  "title": "ff-addon",
  "id": "jid1-mPDAO4AqY5w17w",
  "description": "a basic add-on",
  "author": "",
  "license": "MPL 2.0",
  "version": "0.1"
}

能否请您告诉我什么地方出了问题，或者我可以完成这些简单的功能……非常感谢！

Could you please tell me what's wrong or maybe what I can follow in finishing such simple functions... Thank you so much!

推荐答案

如第一个评论所述，请参阅

As the first comment says, see the documentation for sdk/preferences/service.

这是一个简单的例子:

var name = "extensions.checkCompatibility.nightly";
require("sdk/preferences/service").set(name, false)
