So, you want to stop people from using Firebug when visiting your site? Well, it is just about as easy as you think. All you have to do is basically just see if the firebug console is active. If so display a warning and relocate. The one thing to remember is that you want to prevent this from running when doing cfc calls. This is also true for any other call that does a non standard return.

view plain print about
1<cfsavecontent variable="firebugTxt">
3    if( window.console && window.console.firebug ){
4        alert("Sorry! This system does not support Firebug.\nClick OK to log out.");
5        window.location='/login_out';
6    }
9<cfhtmlhead text="#firebugTxt#">

till next time...
