Video Download Helper is very easy to use when you want to save a copy of a video that you like. It lets yo9u set the folder where the file will go every time. One improvement on that feature would be to tie the download setting in Firefox to where the video is downloaded so you can either have a permanent download folder or let you set the folder on the fly, eliminating having to move the file later.. The notification when the download is done is a nice feature since larger files take longer. I would recommend Video Download Helper to anyone using Firefox!
