This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

There are two things to consider there.

  • All applications which opens with a initial size > 75% of the screen area will get automaximzed.

  • There is a known bugs about some applications, even closed fullscreen (fullscreen and not maximized), where they can't be restored easily. See

Some applications will always open maximized in Unity. It's something to do with their initial size: if they take up more then X of the screen, they will be maximized (I'm not sure what's the value of X though).
