Facebook is one of those social networking websites that each Internet user visit every day. If you have ever wondered about how to download Facebook videos, then here is a Mozilla Firefox add-on carved out from a greasemoneky script namely, Facebook Video.
Facebook Video is a Mozilla Firefox add-on which allows you to download, convert and find the customize code of any video embedded posted on any Facebook page.
Just by clicking on “Download Video” link, you will have that video downloaded on your computer in .mp4 format. And if you click on “Convert Video” link, it will direct you to Zamzar web service, which allows you to convert the video in other formats like .flv, .wmv, .avi, .mp3, .flac, or .wav.
