Most of the sites you'd want to download from have a legal disclaimer and you can't download anything.

Compleatly useless and wants you to buy some stuff 20$ to work

Utterly useless

Doesn't work

Doesn't show videos for download. When I manually show the list, it will find a video, but have no options for downloading. Worthless addon.

does not work

Claims it downloads videos from youtube.
once you install it, you will se a text that it doesn't actually do that.

Don't waste your time with this.

Downloading this video is not possible with a Firefox add-on :-(

very good

it would be great if it's able to download a chunked stream (blob:https//...) as a single file.
when a stream is available as a single file or an *.m3u8 descriptor is present, VLC does the best instead.

not working in Youtube

Works on almost every site, and better than Video DownloadHelper too, which suddenly stopped working for me for no reason at all. Plus there's no watermarks added. Great add-on!
