Rated 3 out of 5 stars

Pros: It works, not a bad idea, it's even restartless.
Cons: Really breaks the browser: even if user is not a developer, it is important for a technician to tell the user to Ctrl+Shift+K (to see current web page console) and provide the javascript error they get. Why does this take away that shortcut?

The idea is to "uninstall" the developer tools. So, the shortcuts are disabled (traditional shortcuts like ctrl+U and ctrl+shift+J still work).
