First off **** 'em.

Secondly, I have a workaround.

But it's not elegant and doesn't work for videos in albums (at present anyway)

Requirements:
* firefox ("minefield" NOT fennec)
* Facebook Video firefox extension (alternatively you may be able to use the port of Greasemonkey and the original greasemonkey script in conjunction with MicroB but I haven't tested it)
* mplayer (or any other video player that can FLV; osso-mediaplayer does not)

1.) Open firefox (the port floating around someone made for Diablo is labeled as "GrandParadiso"; aka one of the developer build codenames)
2.) Edit>Preferences>Set default download folder to /home/user/MyDocs/.videos
3.) Install this: https://addons.mozilla.org/en-US/firefox/addon/9614/ (you will first have to click "allow"), then restart firefox and by this they mean close firefox and re-open it.
4.) Visit a page such as: http://www.facebook.com/pages/Fire-F...r/145513041952

5.) Click "Download Video" link
6.) Choose Save

7.) Open mplayer and select the video (if you use gmplayer it should find the video for you)


What doesn't work:
Videos embedded like such: http://www.facebook.com/video/video.php?v=37403547074
