The only downside to this app is that the download takes a while, and that if you open multple tabs at a time, the button doesn't come up (reload the page, and it usually comes up). Otherwise, it's a very good download app. I like it, and will continue to use it. (I started using it as a replacement for Easy Youtube Video Downloader Express, which I loved, but which stopped working for no reason that I could see).

works good but icon appears late

Works OK so far, mainly 360p quality BUT that's all YouTube provides. some mp4s in Hi Res. This is on windows 8.1 & latest Mozilla at this time.

It's download in split video and audio way, but it works fine.
