For anyone who still uses Firefox, such as me, you'll notice the last Firefox update within the last day has completely changed the Downloads listing. Instead of having its own menu, it has been merged into the Library window with History and Bookmarks. As you'd guess, this is extremely inconvenient. Firefox barely keeps any information on downloads, causing an extreme amount of wasted space in having the entire library open for it. Besides that, when actually conducting a download, you will instead get a popup of a simplified downloads menu which, again, is very unfitting.
To retrieve the old Downloads menu, enter about:config into the address/URL bar above. Click Yes, then enter this in the search: browser.download.useToolkitUI Right click the entry that comes up and click Toggle. New downloads will now appear in the old Downloads menu again. There are some problems, though. Any Add-Ons which modify the old Downloads menu will no longer work. The Downloads menu itself will have no title on the top bar, which means it is not named anywhere windows are listed.
