Works great, it's very rare for this addon to not be able to download a video, it's near universal for just about every video player and site I've been on. Easy to use, you just click the extension, find the right video if there's multiple (there's an animated thumbnail, filename, and length) and hit download. Customizable on how videos are saved, and can also save audio only. I haven't used a single video downloader website using links since getting this. Completely free, too, and no ads. I reached 100 videos downloaded and it politely asked me if I would leave a review. I don't review things often, but this seemed worth the time.
