It doesn't work anymore. It deleted itself from Firefox and for some reason Firefox won't let me add it back on.
It doesn't work anymore to download MP4 on YouTube. There is a message which doesn't help or say they will fix the problem. They more or less say it's your problem. Please fix the problem or admit you can't fix it…
I put your app back to 4 stars… as it works again. Thanks for getting back to me so quickly.
