Migrating from Basilisk. When I downloaded there, I saw merely a blue down arrow flash in the Good Old Sidebar area. That was perfect. Now (back to) PM, when I download, a sidebar panel opens and shows history. I don't need or want that. About:config has browser.download.panel, but that doesn't seem to govern. Its TRUE on Basilisk and FALSE on PM. Any thoughts on how to disable this download sidebar panel? TIA
