This answer still left me confused. Finally I found that the "show in status bar" was unchecked in Preferences/General/ Appearance. After checking that box I had the icon @ the bottom & was back on the road again.
I'm sure it would help if then next time something was moved from the top to the bottom of the page a little notification would help. The Downloader Helper instruction manual still tells you the triangle is up top next to that icon.
