SSH sftp succesful logons

So it seems that it wasn’t as big of a deal as I thought. Someone I knew helped me out and tried to sftp://my-ip, but he got a time out. So it seems that firefox, somehow, is able to connect through ssh. I’m not running ssh-agent on the connecting computer so I’m not sure how it’s able to do that. The firefox connections don’t show up in the logs either (journalctl _SYSTEMD_UNIT=sshd.service -e --follow) besides the time out, which shows as Connection closed by REMOTEHOST
