WDS已断开连接!不断出现

Question

运行webpack-dev-server很好.首页加载正常.但是当我刷新浏览器时,每2秒'WDS disconnected'会出现在控制台和浏览器中无限重新加载.此问题仅出现在Firefox/Firefox Developer Edition浏览器中.浏览器Chrome,Edge,IE11没有问题.

package.json:
....
"webpack": "^1.13.3",
"webpack-dev-server": "^1.16.2"

webpack.config.js:
....
entry: [
    //'app': './app/app.ts'
 'webpack-dev-server/client?http://localhost:8080/', './app/app.ts'

],
output: {
    publicPath: 'http://localhost:8080/',
    filename: 'app/app.bundle.js'
},
....

Firefox Developer Edition 51.0a2
