Firefox is suddenly opening 2 windows on startup OS 13.5.1

Since the arrival of Firefox, I have had it set to open automatically when my computer starts. Recently it has started opening in TWO windows on startup. If I remove Firefox from the 'open on startup' list, obviously it does not start at all. I cannot find any control to make it stop opening two windows. Is it a Mozilla problem, or an Apple problem?

Do both windows show the identical page (your home page), or do they show different pages, or does Firefox appear to be restoring an old session over and over?

Both pages are identical (and slightly offset from each other).
