Selenium webdriver 无法在Selenium 3上启动Json配置的特殊firefox

我使用Selenium网格并通过Json配置节点和集线器 这是我的json

{
  "capabilities":
  [
    {
      "browserName": "firefox",
      "browser-version": "38.8.0",
      "maxInstances": 5,
      "firefox_binary": "C:/Program Files (x86)/secutix/Matterhorn_V3/FireFoxPortableESR/App/Firefox/firefox.exe",
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "chrome",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "internet explorer",
      "maxInstances": 1,
      "seleniumProtocol": "WebDriver"
    }
  ],
  "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
  "maxSession": 5,
  "port": 5568,
  "register": true,
  "registerCycle": 5000,
  "hub": "http://localhost:4444",
  "nodeStatusCheckTimeout": 5000,
  "nodePolling": 5000,
  "role": "node",
  "unregisterIfStillDownAfter": 60000,
  "downPollingLimit": 2,
  "debug": false,
  "servlets" : [],
  "withoutServlets": [],
  "custom": {}
}

我启动了集线器（很好）
我启动了节点（很好）
但是当我通过maven cmd“mvn clean verify”运行serenity测试时 目前只创建了Firefox版本45.6。FireFoxPortableESR为无
如果将Selenium server standalon从3.0更改为2.53，则工作正常。

那么当使用Selenium 3.0*时如何调用FireFoxPortableESR*

您必须添加以下两个键才能使用

Selenium V3.0运行
Firefox
