Works as described unless youtube blocks it again. Remember to keep updating Add-On when it doesn't work as developer constantly patch it.

one of best effective extentions that work always non stop. even when is not update

Good

no hassle updates, can't image life now without this addon

Good to have. We need all the time some music or clip, at that time this is the best addon. You can take the music/clip you want on the road :-). Congrats to the developer, nice job, thank you.

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

Does not seem to work even though it is being updated. Currently v. 16.13

Thanks Dishita for bringing this extension that works. In the past I have tried others and one stopped working after some months.
This is a reliable one. I recommend this to anyone.

Excellent in every respect

The extension is still being marketed as "1080p / 256kbps dl capability" but truth is that even 720p is not available for free users anymore. First they cut 1080, then 720p, hiding behind the same excuses to push the PRO version.
This extension did not build its reputation with the paid version. What can you do with 480p videos in 2021?
