Gave a $15 donation after joining because I was getting 1040p downloads. A few weeks later I could not even download 780p with the following message that I need "pro":
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.

This app does not support HD downloads, only 720p. For HD, you need to pay for the premium version of this app.

Shit addon, just there to grab your money. If you want anything better than potato, this is not the addon for you. I'd wager most of the reviews and installs are faked

Funktioniert nicht. Bei Benutzung wird man aufgefordert, eine Pro-Version zu kaufen.

Reine Werbung, taugt nichts

Developer seems to believe they need a service to convert something. YouTube sends split audio/video streams now. If you want the original video, you'll need to download both and convert them yourself. Of course, the developer could have done this on your local machine with ffmpeg, but decided to do it on a server instead and charge for it. The developer does not allow you to download the HD streams yourself so you can combine them locally.

Use this addon for now: https://cup.aihedy.com/en-US/firefox/addon/youtube-download-hd-download/

Every time I tried to use this extension I got the following quoted message pop up right below the video.
"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.

I have read this 3 or 4 times and I am still not sure if it's an excuse or if they are asking me to buy the "pro version" Does anybody know of a good youtube mp3 converter that works as they say it does? or are all these extension creators all just out to make a quick buck? Sorry guys/gals give this one a pass unless you want to spend the money on a pro version. It does NOT do what they say it does.

não consegui baixar

Every time I try to download something, I just get an ad to upgrade to the Pro version.

Potrzeba zapłacić by działało.

have to pay

Downloading 1080p requires "pro" version, because addon cannot simply connect steams with ffmpeg

HD and better Q only for PRO users
