I haven't found a reliable way, and apparently if I were to it would actually be considered a security issue in the firebug plugin...

Hi, I’m trying to close Firefox when I detect Firebug but with no success…


if (window.console && window.console.firebug) {
window.opener='X';
window.open('','_parent','');
window.close();
}

Firefox doesn’t allow window.close


if (window.console && window.console.firebug) {
window.location = "chrome://mozapps/content/profile/profileSelection.xul";
}

Try the chrome URL in your Firefox, it will close it…

Then I have found the close function directly into the firebugOverlay.xul and firebug.js files but I don’t know how I can call it with javascript

in the xul file : oncommand=”Firebug.closeFirebug(true)”
in the js file :

closeFirebug: function(userCommand) // this is really deactivate
{
var browser = FirebugChrome.getCurrentBrowser();

TabWatcher.unwatchBrowser(browser, userCommand);
Firebug.resetTooltip();
}

If someone know how to do let us know.

The problem is that, being javascript delivered as source code and executing on client machines, it is possible for everyone to read, reverse engineer, modify and do whatever they want with your javascript code.You should write applications that have server side checks to prevent cheating/sniffing/whatelse on the client, cause client computer IS NOT a safe environment, firebug or not firebug.Scripts given in this post are useful to display a warning to the user like "Hey, fellow developer, so you are using firebug ... it can make this site really slow", not to prevent him from looking at your code or "playing" with your javascript, cause there is no way of doing it anyway.

Has anyone else found a way to detect if the other panels, such Net are enabled when Console is not?

I have developed a bebo application, using php and bebo api. But the casual javascript code to disable firebug does not work there. Please, can any body tell me, how i can disable the javascript there, as the firebug is driving me mad, when users crack the game and cheat with the points.
