在firefox控制台中：[WDS]断开连接！一些袜子问题

Question

我在macOS HighSierra的firefox最新浏览器中运行react app，它总是在控制台中显示以下错误

  

[WDS]已断开连接！

msgClose            ...... http://localhost:8080/bundle.js:2517:5    
onclose             ......socket.js:16:24  [5]  
</EventTarget.prototype.dispatchEvent .   ...sockjs.js:170 .  [14]
</</SockJS.prototype._close/<          ..... sockjs.js:965

在Chrome浏览器中工作正常。

我是否需要设置一些设置才能解决此问题？

这是我的 webpack.config.js

const webpack = require('webpack');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin'); // eslint-disable-line
const path = require('path');

const BUILD_DIR = path.resolve(__dirname, 'build');
const APP_DIR = path.resolve(__dirname, 'src');

const HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
    template: './src/index.html',
    filename: 'index.html',
    favicon: './src/assets/favicon.ico',
    inject: 'body'
});

module.exports = {
