Can I turn off the Debug Console window?

After I have installed Unity 5.0.0b18(32-bit) to my laptop, some Unity web games show the debug console window. Can I absolutely turn off it?

Thank you for your answer.

The debug window is only shown when you have the “Development” channel selected in the webplayer.
Just uncheck the option in the webplayer channel menu.

i have the same Problem and i don´t have the development channel selected
