Beware most 5 star reviews for this extension appear to be fake. This extension (at least on macOS) requires additional software to be installed to work, and even if you've already done that it works poorly.

There is probably a better downloader out there - not sure which though.

It did download something from Vimeo which is what I needed, but after running for over an hour, still had not generated a video file in my chosen output directory. Source video was less than 1 hour long.

I discovered that it downloaded a video mp4 and an audio mp4 and was attempting to combine them. After running for almost an hour, it had produced a 12 minute video with a very large QR code taking up about 1/8 of the upper right of the screen.

I killed that process and just ran `ffmpeg -i tmpvideofile.mp4 -i tmpaudiofile.mp4 -c copy mycombinedfile.mp4` and it completed in about 10 seconds.

So in short, this *will* download something for you, but you're better off doing the combining on your own.
