devtools extension doesn't load in detached devtools window

[jhen0409]

• Electron version: 0.37.x
• Operating system: OS X 10.11.3

I used remotedev-extension in Electron, it works well on v0.36.12, but when I upgrade to v0.37, the devtools tab will not displayed.

Are any errors logged to the terminal when you click the tab in the dev tools for that extension?

The problem is BrowserWindow.addDevToolsExtension(...) returns undefined, this means it not loaded.

manifest file here

@kevinsawicki I found that when I would separate Developer Tools window and restart Electron process, the devpanel will not displayed. Looks it's not problem of this extension.

I also created a tiny extension, it have the same problem:

Undock into separate window & restart program:

Try append script below in your app’s main script before the ready event of app module is emitted: (ref : Supported Chrome command line switches)
app.commandLine.appendSwitch('remote-debugging-port', '8315');
app.commandLine.appendSwitch('host-rules', 'MAP * 127.0.0.1');

Open google chrome browser and go to http://127.0.0.1:8315, continue activating the dev tools, and you'll found some error occured. In my case, the Object.observe has been deprecated.

I believe this has been fixed by the Chrome 50 upgrade. I am no longer able to reproduce it in the Electron 1.1.0 release so I'm going to close this out.
