Very Good. I think it could have been better if it provided the shortcut feature that I can manage in Firefox Add-ons Manager. Nevertheless, the developer has commented below that he implemented 'right-click', so it might substitute the shortcut.
Two tweaks would make this a 5-star must-have add-on: 1) keyboard shortcut (ctrl+m is popolar for competing add-ons) 2) setting for default AI to use when clicking the button
