This only occurs if create-react-app creates the browser process itself. See info below.

Environment

1. node -v: v6.11.3

2. npm -v:5.4.1

3. yarn --version (if you use Yarn):

4. npm ls react-scripts (if you haven’t ejected): [email protected]

5. Operating system: Ubuntu 16.04

6. Browser and version (if relevant): Chromium 60.0.3112.113

Steps to Reproduce

1. Without a browser open, run npm run start in a repo created with create-react-app
2. Open a few tabs in the browser created by that command.
3. Ctrl-C the react server.

Expected Behavior

The browser remains open. Or maybe gives a confirm dialog, then closes.

Actual Behavior

The browser closes, losing my open tabs.
