I found this looking for a way to download videos (my own for backup reasons) from YouTube using Google Chrome. Someone else might find it useful.
The script works in:
- Firefox (install Greasemonkey or Scriptish first)
- Google Chrome (no plug-in required, just click "Install")
Opera (no plug-in required, save the script to the User JavaScript folder)
- Safari (install GreaseKit first)
- Internet Explorer (install IE7Pro, download the script, change the extension to .ieuser.js, copy the file to c:\program files\iepro\userscript and enable the script in IE7Pro's settings dialog)
