Set proxy using google chrome extension

I am trying to build a chrome extension which can change proxy settings when the fire up the browser. I have followed the chrome extension documentation but still no success.

manifest.json

   {

      "manifest_version": 2,

      "name": "Proxy",
      "description": "Proxy on 127.0.0.1:8080",
      "version": "1.1",
      "background": {
      "scripts":["background.js"]
      },
      "browser_action": {
            "default_icon": "icon.png",
            "popup":"popup.html"
        },
    "permissions": [
        "tabs",
        "http://*/*",
        "https://*/*",
        "notifications",
        "contextMenus",
        "history",
        "background",
        "proxy"
    ],
    "content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'"
    }

backround.js

chrome.windows.onCreated.addListener(function() {

var config = {
  mode: "fixed_servers",
  rules: {
    proxyForHttp: {
      scheme: "http",
      host: "127.0.0.1",
      port:"8080"
    },
    bypassList: ["foobar.com"]
  }
};
chrome.proxy.settings.set(
    {value: config, scope: 'regular'},
    function() {});

});

The above code doesn't works...

"when the fire up the browser"

You Should use Chrome.Runtime instead chrome.windows.onCreated. Use chrome.runtime.onStartup, So When Browser is open from nothing hrome.runtime.onStartup will fired.

onStartup Fired when a profile that has this extension installed first starts up. This event is not fired when an incognito profile is started, even if this extension is operating in 'split' incognito mode.

It Will Be Like This

chrome.runtime.onStartup.addListener(function() {
var config = {
  mode: "fixed_servers",
  rules: {
    proxyForHttp: {
      scheme: "http",
      host: "127.0.0.1",
      port:"8080"
    },
    bypassList: ["foobar.com"]
  }
};
chrome.proxy.settings.set(
    {value: config, scope: 'regular'},
    function() {});

});

also you can use onInstalled for when you install / update the extension...

proxyForHttp: --> singleProxy:

and

port:'8080' --> port: 8080

Change the line port:"8080" to port:8080 and it'll work.

You can check effective settings at chrome://net-internals/#proxy.

Nicety

If via PAC script, on script code error, chrome.proxy.settings.set handler still runs even as the proxy fails silently. This can be detected at chrome://net-internals/#events.

Nicety

This page claims that console.log messages in your PAC script can be found in net log, but it doesn't seem to work.

It shouldn't be a problem with the background page. Your code is in the onCreated event on the window object. You are not guaranteed to have the extension loaded by the time the first window is created.

Simply remvove the event and have the code run, you should then have it run once when the extension is initialised.

i don't think you can use the chrome.proxy API from Background.js. i did the same with a pop-up extension (used the code samples from the documentation) and it works perfectly...
