[ionic-app-scripts 0.0.45] Browser not opening automatically

Opening a new thread to clarify the discussion started here

When starting a new Ionic 2 project based on tabs and performing:

ionic serve -c- s

the browser does not open automatically. The page must be manually loaded first, but then reloads when code changes. This happens on Ubuntu 16.04, where default browser is Chromium Version 53.0.2785.143. This happens since 0.0.44, maybe 0.0.43, but there I had others problems (see previously mentioned thread if you feel it is relevant).

Info:

Cordova CLI: 6.4.0 
Ionic Framework Version: 2.0.0-rc.3
Ionic CLI Version: 2.1.12
Ionic App Lib Version: 2.1.7
Ionic App Scripts Version: 0.0.45
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Linux 4.4
Node Version: v6.9.1
Xcode version: Not installed

npm v4.0.2

BTW when starting, there is a warning:

Config file "/home/jrierab/ionic2/testBuild45/--" not found. Using defaults instead.

Maybe it is related to what Lis was commenting here

Dan, If you need more info/test don’t hesitate to ask.

Same problem here with RC3… Says dev server running: http://localhost:8100/ and then nothing…
