Find out if Developer Console is active in the current webbrower (JavaScript)

Question

While developing a logging tool for websites, especially for javascript code I need to know if the Developement Tools (IE: Developer Tools, Chrome: F12, Firefox: Firebug etc.) are open.

Until know the only possibily I have found in my research was to get it in IE10 by asking for

window.__IE_DEVTOOLBAR_CONSOLE_COMMAND_LINE

Are there any variables or functions which can be called in Chrome, Firefox (and Opera) to get the status of the browsers Developent Tools.

I know there is the console object but this object does not tell me if the DevTools are open or closed.

You might find this other SO thread useful: Find out whether Chrome console is open

There is some good information about both Firefox and Chrome in there.
