Before time, I know how to download Youtube video with http://keepvid.com. This site is cool because we can download all types of Youtube video without installing any addons or softwares except Java Applet. Unfortunately, we cannot download Facebook video with this site and I don't know why.
Today, I know how to download Facebook video without installing any addons. Ok, I don't waste your time and let make it short.
- Open one of videos from Facebook
- Just play one or two seconds (but it's optional)
- Select this video player and right click on it. After that, you will see prompt message will be coming out and click on View Selection Source
- Then, HTML source code of selection will be coming out. Find this word "video_src=" into this coding and copy the message after this and till to "motion_log". You need to note down this copy URL encoded messages.
- Go to www.string-functions.com/urldecode.aspx and transform this URL encode message to decoded message.
- Finally, you will get the URL of Facebook original video file and download it.
- ENJOY...!!!

After decoding URL, remove this one, <b>&</b> from URL and it will work fine.
