Facebook videos are increasingly becoming popular for last few months. Every day we see some new video being uploaded by friends. It now serves more than 1 billion impression a month We have numerous tools to download youtube videos, but what about facebook videos.

Downloading facebook videos could be achieved by at least two means. One of the option is to download and use IDM ( Internet Download Manager) to download any facebook video you wish to. But  to avoid this means of using a third party software, one may use the new firefox addon to download any facebook video.

This Firefox addon is called – Facebook Video. This addon after being installed can be used to perform number of functions with the videos on Facebook. It adds four options under every video -  Download Video, Convert Video, Embed Video, and Customize Code option. So one can do a lot more than just downloading the video.

Clicking the Download Video will start downloading the video instantly in MP4 format. For converting the video it uses an online service called Zamzar where a user can convert the video to several formats and receive a link in an email to download the converted version. The customize code link opens a dialog to change the resolution of the embed code and/or select the auto-play option. Once the user selects “Update” the embed code in the box is changed to reflect the users preferences and the video will also be replaced so that they can view the immediate result of their changes The rest of the options can also be used effectively.

It was originally developed as a GreaseMonkey script but to make it further easy for users(to install), the developer has converted it into an add-on. It works on Firefox version 2.0 and newer including version 3.5
