How do I disable script debugging in Visual Studio 2013? I have already disabled script JIT debugging under Tools>Options>Debugging>JIT, and have turned off script debugging in Internet Explorer as well. Despite setting the error option to 'break when an exception occurs' unchecked, Visual Studio still breaks when a script error occurs specifically in IE. The error only appears in Firebug/debugger window for FF and Chrome. Is there another setting that needs to be adjusted in order to exclusively use the browser debugger?
