An attitude one might receive after questioning why an expected feature or function of a product or thing is either missing, broken, or implemented in a non user-friendly manner.

Mozillatude often comes in the form of a question, thrown back in one's face: "Why would you want to do that?" or "If it bugs you, why don't you stop complaining and fix it yourself?"

Term comes from the seemingly overly-prevalent attitude among those responsible for the development of Mozilla-family Internet products (Firefox, Thunderbird, Mozilla Suite), especially after an issue or complaint has been brought up.
