I am using the internal server of WebStorm (63342)
If I debug in Chrome (Version 35.0.1916.27 beta), the program did not stop on the breakpoints.
Chrome contains the plug-in JetBrain IDE support 2.0 that seems well installed.
IDE Connection --> Host: 127.0.0.1 --> Port: 63342
If I use Firefox (with JetBrains FireFox extensions 0.6.1), it works well and stop on the breakPoints.
Thanks a lot
