В связи с политикой Youtube это расширение потеряло всякий смысл для free use: для сохранения в режиме 360р/128KB/s достаточно хорошо себя зарекомендовавшего и более универсального Ant Video Downloader.

Downloads videos yes, but it's also very intrusive. It invades the graphical interface of Youtube with not only the button, but also a big message about a premium product when I tried to download an MP3. I could not remove the message until I uninstalled this. Bad decision on your part.

The very intrusive message is:
PRO UPGRADE : Since Youtube no longer provides direct download links for 1080p and MP3 qualities these two qualities require server infrastructure for processing, therefore user needs to Pay and Upgrade here >>>, you have the choice to pay whatever you want for this one-time upgrade which helps me keep this service alive for all users.

It puts their logo throughout the video which sucks big time. Otherwise was quick and trouble free.

The ONLY add-on I've found that downloads HD videos. Works great on nearly everything, though I've run into one or two videos that it couldn't download.

Update 7/23/20: Software has been updated to change the way it activates for the pro version. Only people who bought in the last 12 months get to keep using it. I paid for pro 15 months ago so would need to pay again but I will not. Dropping my rating considerably for this.

As of 5/23/2021, every time you want to download it, it will take you to a tab names youtube.com/undefined. I have been refreshing it MANY times and nothing! First the missing Download button, and now this! This needs to stop! I hope they fix this SOON!

yes

This plug-in used to be great. Recently, however, it breaks on a weekly basis. There are much better youtube downloaders that never break: video download helper and youtube download button being the two best.

When this one works, it's awesome. The problem is it rarely works.

Worked for 1 download. After the first download only empty 0kb downloaded files

Mp3 Download don´t work at all anymore!!!

Youtube switched to separate audio/video streaming technology for higher quality formats and no longer provides direct 720p (Since 24 September 2018)/1080p/mp3 streams. Converting these streams to downloadable formats for you needs powerful server infrastructure, therefore 1080p/mp3 downloading has been limited to PRO users. Read more at - https://videodroid.org/pro_upgrade.html. FREE users can download all formats in CACHE where some PRO users fetched the video/audio in past 24 hours, to test the feature you can try downloading popular videos.

Not working. Downloads 0 bytes.

9xbuddy.com is better because you don't need to pay for 720p or 1080p

Works great for a while, then the activation expires after a few weeks and I need to pay yet again. I wish they would post the amount you need to pay to make activation permanent. If they do have an amount, it's more than $50 US. Even when you do pay, activation is extremely difficult. The help links just go around in a circle. Click here takes you to another click here, which goes back to the original click here, and so on.

1080p or mp3 download is available only for pro version.. though they ask us to wait for an upgrade to download 720/1080, i dont think its reliable.. Its just like any other downloader.. there are better alternatives available.. IDM may be ideal and a better option. thanx..

This downloader doesn't let you download Youtube videos with both the video and audio. I don't know why Youtube downloaders think people EVER want just one or the other. This extension HAS the ability to download both but it won't let you until you download their app. What's the point of installing the extension then?

i couldn't make it work

They don't send out a re-activation e-mail as they claim to do.

Payment only possible with the creation of a PayPal account. If you refuse to create a PayPal account, no payment is possible. So, goodbye, without me.
