It is a paid addon. And even then they don't offer you 1440p or 4K resolution. 480p is missing.
360p is available in the free version, but it didn't work for me (got an error).

Works, but subtracted a star for a weird issue I had and can't replicate. Yesterday I could not get this to work , re-started browser, rebooted PC, cleared cache etc app refused to work. Today it works flawlessly. Maybe you have to wait a few hours before using the pro features after upgrading?

I gave thirty dollars then had to re download and am not pro now???? Can.t find where to sign in again without donating again....???? It did work most off the time.

YouTube apparently changed their code again or something, thought these guys were hiding behind a paywall but the other online downloaders I went too either aren't showing 720p or do but the link to download doesn't work.

will let you know once used.

I loved this extension but more recently I've had trouble downloading some youtube videos

being forced to review this to update to latest update? I think idk when it worked it was cool but yt blocked my version and updating anything always seems to be a pain

Ultimamente no
reproduce los videos

When its working its great.

i use it

I still get 'The following content is not available on this app .........' when I download a video. This add-on was a very good add-on before. Hope you will be able to fix the problem soon. Thank you.

was working very well.. until around a week ago or so..
