You don’t need to have FF tell sites not to track you, but personally I feel there are many sites that would love to be able to use your activity to build a history.
CookieMonster and do not track are completely separate so you don’t have to set do not track to use CookieMonster.
I don’t see any attached image that you say was attached. That however can have many reasons, some add-ons in firefox may give additional options/settings; the Operating System and or using a different Theme in your operating system can change the look of the displayed window.
