Application.OpenURL crashes Firefox on WebGL

Question

Hi folks, I'm new to Unity.

I use following code to quit my application, but the WebGL build crashes my Firefox when I call Application.OpenURL(). WebPlayer build works fine.

 void Update ()
 {        
     // Exit game?
     if (Input.GetKeyDown (KeyCode.Escape)) {
         if (Application.platform == RuntimePlatform.WebGLPlayer
             || Application.platform == RuntimePlatform.WindowsWebPlayer
             || Application.platform == RuntimePlatform.OSXWebPlayer) {
             // Browsers go back to home
             Application.OpenURL ("http://localhost/");
         }
         #if UNITY_EDITOR
         else if (Application.platform == RuntimePlatform.WindowsEditor
             || Application.platform == RuntimePlatform.OSXEditor) {
             // Editors stop game mode
             UnityEditor.EditorApplication.isPlaying = false;
         }
         #endif
         else {
             // Standalone builds just quit
             Application.Quit ();
         }
     }
 }

Is this a known issue? Or, I should not even use Application.OpenURL to quit my browser application?

Some spec reports:

Unity 5.1.0f3

Firefox 38.0.5: WebGL - Crashes on Application.OpenURL

Chrome: WebGL - Works fine

IE: WebGL - Whole app crashes (I know it's not well supported yet, so it's ok.)

There seems indeed to be an issue. I reported it as a bug and sent it to the developers.

OpenURL indeed does not currently work on WebGL. You'll need to create a simple javascript plugin to handle onMouseUps, and handle your onMouseDowns to send events to said plugin. It sounds complicated, but it's simple once you get it. But you'll probably lose a couple hours to get it working the first time: http://va.lent.in/opening-links-in-a-unity-webgl-project/
