So, here is the back-story. There is a Firefox extension called Greasemonkey which allows the user to build a library of scripts that change web pages. They automate tasks, and creating a script for Greasemonkey is much easier than writing and publicizing an extension.

Apparently there is now a script called Netflix Download Links which automates the long process of finding, hacking, and downloading a Netflix streaming movie.

DISCLAIMER: Download these movies at your own risk. This is a questionable process as you pay for the service, but are still violating copyright laws. In addition, it is possible to get your account banned for this. Don’t come crying to us if this doesn’t go well.

Now that we’re past that little bit, let’s get in to the details. You DO have to have a subscription to Netflix to do this. The script claims that it works on all platforms, but if you’re using Vista it is reported to have problems. The non-windows user will need to set the variable "IAmRunningWindows" to false, and you’ll still need a Windows machine or a Windows emulator to remove the DRM. For more help with this, you might want to look through the comments on the article that I heard about this from.
