How to Download a Facebook video

I see this question a lot, the answer is very simple..

Situation: someone on Facebook shared a video you want to download to PC

1) The post title says something like "John Doe shared Amazing's Video".
2) Click on the word <Video>, this will bring you to the original video.
3) Go to the URL-bar in your browser and replace <WWW> with <M>
4) It should become something like: https://m.facebook.com/story.php?story_fbid=......
5) Right click on the small video thumbnail and choose <Save video as> or <Save target as> or <Save source as>.
6) Name the video and choose a destination folder on your PC..

Have fun  :P
