Use Strict : How to test it?

I have been reading people recommending using "use strict" option. As mentioned here

every major browser supports strict mode in their latest version, including Internet Explorer 10 and Opera 12. I wanted to test it with IE10 and i have following code segemnt. IE 10 /FF did not gave any error message. What am i missing ? How do i test that "use strict" is actually working if i make any mistake ?

<html>
<head>
<script type = "text/javascript">
"use strict";
function doSomething(value1, value1, value3) {
     alert('hello');
}
</script>
</head>
<body>
hello
</body>
</html>

firefox throws 'duplicate formal argument value1',

IE10 throws 'Duplicate formal parameter names not allowed in strict mode'

You can see in this example that Chrome actually complains about the duplicate argument name:
