I wrote how to download Facebook video Download Facebook video without installing addons in my old post. At that time, Facebook using "embed" tag as displaying their video and it's easy to get original mp4 video from Facebook. Yesterday, one commenter wrote that he cannot download Facebook video regarding the instruction of my previous post. I was confused and cannot understand why he cannot download at all. That's why I've open Facebook video page and reviewed source code of it. Oddly, Facebook don't use "embed" tag as displaying their video anymore and changed their coding for using javascript as displaying. That's why I need to find out how to download original mp4 file of this movie from Facebook again.

Now, I write some simple javascript coding to get the original video of Facebook. In this coding, I need to convert hexcode to string with javascript and decode it again.

1FacebookURL = FacebookURL.replace(/\\u00253A/g,":");
2FacebookURL = FacebookURL.replace(/\\u00252F/g,'/');
3FacebookURL = FacebookURL.replace(/\\u00253F/g,"?");
4FacebookURL = FacebookURL.replace(/\\u00253D/g,"=");
5FacebookURL = FacebookURL.replace(/\\u002526/g,"&");
6FacebookURL = FacebookURL.replace(/%3A/g,":");
7FacebookURL = FacebookURL.replace(/%2F/g,"/");
8FacebookURL = FacebookURL.replace(/%3F/g,"?");
9FacebookURL = FacebookURL.replace(/%3D/g,"=");
