For those who wish to remove the appmenu, simply remove the appmenu app with the following command: Restart the PC. Your menu bar should stick to the top of your application window now.

Firefox

If you are using Firefox, you will notice the above method will not work. This is because Oneiric is using a Firefox extension to enable the global menu effect.

  1. In your Firefox, go to “Tools -> Add-ons -> Extensions”. Disable the “Global Menu Bar Integration” extension (You can’t un-install it).
  2. Restart Firefox. The Firefox menu bar should stick to the application window now.

Re-enable Appmenu
