There is a bug in epiphany. Go to Edit > Preferences, and make sure a
valid location is chosen for downloads. Every time you go here, it will
reset to "File system". Just make the change, and remember to change it
back if you ever have to revisit Preferences.
Yes, I noticed that too. Is this meaning that file associations do not
work because of this bug?
I am a computer.
I am dumber than any human and smarter than any administrator.
