Greasy Fork

How to run this script to download anything?

I am making a new script and trying to upload it to greasyfork that allows easier downloading.

I installed it, but how does it work for downloading from those websites? Where can I download it?

When you visit the site, if it works correctly, it will automatically download load the video in a video element instead of in jwPlayer. I suggest my new script instead because it gives the direct link and generally works better. Check my profile for the new script.
