Easy YouTube Video Downloader

Often there are YouTube videos that you need to download for offline viewing or for a project.  There are plenty of YouTube download add-ons for Firefox, but I found my favorite:  Easy YouTube Video Downloader.  It's a simple add-on and the only configuration you have to mess with is the download location. After that, the Easy YouTube Video Downloader simply inserts a download option on the right underneath the video information:

Just click on the video format you'd like (FLV, 3GP, or MP4) and the video automatically downloads to the folder location you have set. Easy!
