I had same prob. Solution for me was simply to use different browser for this (Linux: Chromium Web Browser instead of Firefox).

Linux PC desktop backup to Linux LAPTOP by running FFS on desktop:
Laptop is available on PC filemanager (having setup shares on laptop via samba and Nautilus).
But problem backing up some files (LuckyBackup) from PC to Laptop.

I think I fixed this in past by running FFS as admin,
so I can copy ...
