Good for low-definition but when I tried to download a 1280p gave me this SOB story in a massive pop-up:

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.

So, yeah, I simply tried a different Youtube downloader Add-On and 1280p was no problem for it at all - no SOB story or asking for money, just quick 1280p download.

Dishita, you have been uninstalled.
