Mozilla just released Firefox 20 (download for Windows | Mac | Linux), which introduced a few new features, including a brand-new download manager. The new download manager works similarly to the old one, but with a couple of new twists.
The first change you'll notice is a new Download button next to the Home button. This gives you quick access to the last three downloads. The Download button will actually display the time remaining during a download, then change to an arrow when the download completes.
You can click on "Show All Downloads" or use the keyboard shortcut, Ctrl+J for Windows and Command+J on a Mac, to see all your downloads in the Library. All of your downloads are now listed in the Library, where you can also manage your browsing history, bookmarks, and tags.
From the Library, you can pause a current download, open containing folders, go to the download page, copy the download link, remove individual files from history, or clear the entire download history.
According to Ghacks, if you don't like the new Firefox download manager, you can go back to the old one by toggling a preference in about:config. Just type "about:config" in the address bar, then search for browser.download.useToolkitUI. Toggle the preference from the false value, to true. The old download manager will now be enabled.
That's it. What do you think of the new download manager? Will you use the new one or switch back to the old?
