UPDATE: This still is fine for 2.0.0.x, but UnPlug does not run properly on Firefox 3 and later, so if you’re on 3.0, this unfortunately will not work.

Firefox extension UnPlug is a very useful tool for extracting embedded video from all sorts of websites.

It can be a bit alien to work out how to use at first though, so I’ve put together a quick video of just over a minute that walks you through the process. It assumes you’ve already got UnPlug installed and loaded into Firefox.
