If you remember, I’ve already posted a blog entry with the same title. As an update, I decided to make another one. Since the userscript that I mentioned back there isn’t working anymore. Tried and tested on Firefox 3.6 and Firefox 4. Officially it doesn’t work. I’m referring to Youtube HD Ultimate userscript.
This time around. The userscript of choice is download youtube videos as mp4. Yeah, they’re not too creative in naming their userscript but it works. If you haven’t captured the first link here it is again.
Be sure to install Greasemonkey first and then restart Firefox then install the userscript. Access the youtube video that you want to download and from the bottom of youtube video you will see a new button called download. Just choose what format you want to download the video.
