There are a few videos on YouTube I wouldn’t mind saving to watch later – take this one for example. Come on, I know you could all watch my Web hosting stress relief video all day long. Why go get a new extension to do a job I can do myself with a simple Greasemonkey user script? This is all you need to do – pick up the YouTube Video Download script at userscripts.org for Greasemonkey.

After doing so – you get a pretty little download icon as you see in the image above where you can download any video from the Web site. You’ll get it as an .flv file. Then you can play it in that format using a player like VLC Media Player or convert it to something else.
