I am not much familiar with Linux and cannot find the default directory where the Firefox stores downloaded files. Firefox' Preferences window says just "downloads" without any path to the directory.

That should be in your home with the name Downloads unless otherwise changed by yourself or another user using your account.
That is a direct reference to Ubuntu default folders and can be changed by editing the file ~/.config/user-dirs.dirs with a text editor, using for example leafpad:
leafpad ~/.config/user-dirs.dirs
# This file is written by xdg-user-dirs-update
# If you want to change or add directories, just edit the line you're
# interested in. All local changes will be retained on the next run
# Format is XDG_xxx_DIR="$HOME/yyy", where yyy is a shell-escaped
# homedir-relative path, or XDG_xxx_DIR="/yyy", where /yyy is an
# absolute path. No other format is supported.
#
XDG_DESKTOP_DIR="$HOME/Desktop"
XDG_DOWNLOAD_DIR="$HOME/Downloads"
XDG_TEMPLATES_DIR="$HOME/Templates"
XDG_PUBLICSHARE_DIR="$HOME/Public"
XDG_DOCUMENTS_DIR="$HOME/Documents"
XDG_MUSIC_DIR="$HOME/Music"
XDG_PICTURES_DIR="$HOME/Pictures"
XDG_VIDEOS_DIR="$HOME/Videos"This functionality is provided by the package xdg-user-dirs installed by default in any Ubuntu flavor.
I found that firefox doesn't actually use the Downloads folder. Instead it puts everything in /tmp/mozilla_username0
