My free favorite is Free Download Manager with Firefox :-TU You will see download it with FDM! button up on the videos and it will automatically catches files that you download. It makes me feel like IDM. I recommend it. (video converter and Bittorrent plug-in in it, too)
maybe you can use JDownloader but it is so hard to use.
