Firefox and USB external drive

I have an external USB SSD drive that I use only to manually copy occasional data files for backup. No program files are on that drive. When I want to disconnect the USB drive with ONLY Firefox running, Windows tells me a program is using the drive. When I close Firefox I can disconnect the drive normally. There are no Firefox related files on the drive - not even manual backups.

Why is Firefox using my USB drive? How do I stop such access?

Thanks, David
