Parental controls are not available on FMovies since it's not a legitimate streaming site. It doesn't have child-friendly filters for any of its content like on subscription platforms such as Netflix and Disney+. If you don't want the children to access inappropriate content, it is wiser to stick to streaming services that are legal and include parental controls. An FMovies alternative like Amazon Prime Video or Disney+ provides parental control options so that parents can restrict what their kids can view.
