I've been a faithful user of Download Statusbar, since before it added the "S3" to its name. Before the WebExtensions revolution came to break down all add-ons, I forced myself to get used to live without it. Now, who could tell, there is a WE version of it! And not only that, but it's even more useful than the former XUL add-on! Without "DownThemAll", the [Create new download] option is a life saver, absolutely essential!
