Its easy to use. Just click Quick Download & wait for it to finish. No Trials or Fee, Its Free.

One of the best Downloaders. But last few weeks there's an error on many Youtube-Videos: "Cannot detect url_encoded_fmt_stream_map or adaptive fmts".
Please fix it :)

I wish I could give me more rating. Its best for youtube download audio and video. Must try guys

Good software. I like to use this.

Will not download most videos in 720

Was working perfectly, but youtube has now changed how they deliver videos.
Waiting patiently for the various video downloaders to come up with a workaround.

Update, have just revisited youtube and the extension now seems to be working again, perhaps google have reinstated whatever it was that broke the downloaders earlier.

update 20201104
new version fixes the annoying permissions and other errors that have happened since the FF update from v81 to v82 :)
The best youtube video downloader is back (happy dance)

Does not work. On any YouTube video, clicking the download button just results in "Cannot detect url_encoded_fmt_stream_map or adaptive_fmts"
