Seems to be currently the only FF extension able to download 720p/1080p video, and only after a donation. So even though you're not required to pay, this uses the freemium model. Sucks though that the main thing I need right now for a project I'm working on is to download 480p video and I can't seem to find any program that still does that.

i use this plug in almost every day and it works great. every once in a while it will have a bug but over all the experience is excellent!

Great downloader, thanks for your good work. It is helping me so much to do well in my studies.

I love this app. It downloads both video and audio with incredible speed and is easy to use.
