I am truly grateful for this addon. I use it frequently and appreciate the flawless operation and playback it provides. Gives me the opportunity to watch chosen videos offline at my convenience. Thank you.

Used to work great the first time but now, a week later, nothing happens. Don't understand why...

Despite claims to be compatible with Firefox 42, it actually requires a minimum of Firefox 52.
