Facebook does not have a native way to downland it’s videos. Unfortunately You have to rely on 3rd party services for that. I found this Firefox add-on called “Facebook Video” which allows you to download Facebook videos as MP4 format in just one click.

How to ?

You must have Firefox installed for this to work.

Install the “Facebook Video” add-on from here

Note:- You will have to restart the firefox for the installation to take effect.

That’s it! From Now you will see a ‘Download video” link under every facebook video you see.

Download Facebook video

This add-on also allows you to convert Facebook videos in to any format throught another 3rd party online service called “ZamZar”.
