How to block developers tools (like Firebug) in a page?

问题

I need to block tools like Firebug and Chrome Developer Tools in a specific page. How can I do that?

I found this code and it works for Firebug:

<script>
   if( window.console && window.console.firebug ){
      alert("Sorry! This system does not support Firebug.\nClick OK to log out.");
      window.location='/login_out';
   }
</script>

But not for Chrome Developer Tools and others. Does anyone know a way of blocking it to most of developer tools?

Just FYI, I need this to avoid users to change the html code. I'm using hidden inputs in a form, and sadly, I really need to do this instead using cURL or something similar. Sorry if "developer tools" was not clear enough.

Don't bother. You can't disable it, and frankly - there's never a good reason to do it. Don't send your users anything you don't want them to see.
