Just to check, by "close window" you mean quit the app? Because on macOS if you close the window first (the red "x" traffic light button in the corner of a window) all you're saving in the session is an empty state with no windows or tabs.

yes i exit by closing the window with red X tab

In that case on macOS you'll always only ever get empty session restore.

Next time try via menu Firefox › Quit Firefox with windows still open to see if that saves your session correctly.
