Not a perfect solution, but you can add breakpoints on the events Window.close and unload by turning on the checkboxes at:

Developer tools -> "Sources" tab -> Event Listener Breakpoints -> Window -> close

And

Event Listener Breakpoints -> Load -> unload

Try to mark both and see which one works best for you
