$$$ : another lucrative money-making enterprise.
I've payed for the PRO upgrade to download 1080p vids, but the feature fades out with cookies or something. The extension designer doesn't respond to emails or tells me to pay another time. How pitiful.

***** ALL STAR RATING FROM ME!!! I am very impressed with how simple and fast it truly is when downloading youtube videos. I have used other downloaders before I found this one & yours truly does exactly what it says. I have shared with people i know and i am sure they will be impressed as much as i am. I do only use the free version at this point as i am unable to work right now or i would give a donation to upgrade if i could. You deserve to be rated #1 in my book, so i just wanted to take a moment and give you all the props you deserve. THANK YOU SO MUCH!!! THIS DOWNLOADER IS BY FAR THE BEST & i am grateful !!!

簡單好用, 但要先付費贊助. 另外付費後用了三四個月後莫名無法使用, 要再付費開啓.

If you want to download music, tough luck.

wants you to pay to DL 720p or 1080p, doesn't even see 4k streams

excuse given for the need to charge for "pro" is "server infrastructure" or some nonsense, as if they couldnt just use ffmpeg or something similar on your local machine to combine the streams

I mean I can do that manually with mkvmerge ffs takes like 1 second for 5min 4k video

F

You don't need "server infrastructure" to download and merge DASH, you only need FFmpeg and a command line. There are free utilities anyone can use. Ridiculous.

Please let us know when and if this add-on will be available for use again. It has been great in the past, and I have sent money a number of times.

Awesome extension. My experience has been excellent.Hope it would continue in future too.
This is very best extension as for as you tube downloads are concerned. I recommend this to all users of firefox.
However in recent months , may be for about 4 to 5 months not working, It always says that it has been blocked by youtube. Even though button shows to be active and when pressed says it is getting connected but gets the video in mp4 or mp3 version.
Let us know what is the problem. Some people reported even after paying money bought the app for it, it does not work!! Really bad. I saw that site YT1s works well, then why not this app , which many YT users depend on.

UPDATE 10/28/2025: Loved this add on 7 years ago and gave it a 5 stars. But now it's not working right; I get 3 downloads buttons under the video. There is no place to report the problem for help. I deleted it a few times and reinstalled hoping it would clear itself out, but no luck. Now I give it 2 stars.

I paid 30$ but don't get the service

Some features are only available for "PRO" users.

Not too useful: can't download private videos, and can download mp3s only in 256 kb/s bitrate. High quality (320) is not an option. Some higher functions are available only in paid form.

Nothing extra, doesn't do anything else other apps also do.

Не качает в 1080. Только в 720. За 1080 просят купить.

This add-on is functionally well but it frequently stop working and ask to donate again.

not work 1080p

Doesn't work with 1080 p or mp3... the description of this add on is false for a long time.
