Error on reloading page in the initial next.js installation

Describe the bug I get the following error shown in the console when I reload a page in firefox: The connection to http://localhost:3000/_next/webpack-hmr was interrupted while the page was loading.

This seems to happen even with a new next.js installation.

To Reproduce

• Create a new folder mkdir nextjs-test
• navigate to the folder and install dependencies npm install --save next react react-dom
• add the dev script to package.json "dev": "next"
• create ./pages/index.js and copy the following code: export default () => <div>Welcome to next.js!</div>
• npm run dev and open localhost:3000 in firefox.
• Reload the browser and open the console. The error should show up in your console.

Expected behavior I expect no error since I only followed the basic setup.

System information

• OS: macOS
• Browser: firefox 60.0.1 (no error when using chrome)
• Version of Next.js: 6.0.3

Same, only with firefox.

@timneutkens can this issue be reopened? Or should we create a new one, separate for Firefox issues?
