How can I get Firefox 5 Mac to warn me before quitting?

Use Firefox 4, a warning dialog box was displayed until I leave the browser. This warning is essential for me since I work through a web application and risk losing work if I accidentally left. I often use Cmd + W to close tabs and Cmd + Q is a swipe of the finger.

I have the following configuration settings:

browser.showQuitWarning = true
browser.warnOnQuit = true

Is it possible to retrieve the dialog box confirmation to quit smoking? You can also work around this problem, is it possible to remap or disable the shortcut Cmd + Q?

You have a try if you can disable this shortcut with this extension.
