我正在尝试Chrome扩展程序在同一标签页中逐个打开列表中的URL。当一个URL被打开时，我希望列表中相应的序列号可以作为打开的页面控制台中的一个变量。

{
  "manifest_version": 2,
  "name": "URL Opener",
  "version": "1.0",
  "description": "Open URLs from a list and execute code snippets.",
  "permissions": ["tabs", "activeTab"],
  "browser_action": {
    "default_popup": "popup.html"
  },
  "content_scripts": [
    {
      "matches": ["<all_urls>"],
      "js": ["content_script.js"]
    }
  ],
  "web_accessible_resources": ["execute_code.js"]
}
