crapware

Trying to dl as a 128 kb/s mp3 audio (lowest available and only audio format available) resulted in a prompt for the pay version (one-time $10 minimum). Means no music for me. I'd be fine with free m4a, which e.g. jDown offers me by default without conversion.

Removed almost immediately as it does NOTHING but try to upsell you a 'pro' version... It DOESN'T download videos of ANY resolution - and is a complete waste of your time!

Funktioniert nur in der Pro-Version für $30.

Comment of the add-on, when it should work:
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.
Kicked off.

Payware. EXPENSIVE payware. Does not allow free downloads anymore (and MUST say so in product description). Until they fix that, one star.

Doesn't actually allow you to download, ...anything. Used to work great. Now they require you to pay to play.

Piece of crap software doesn't want to download anything without a paid upgrade

Complemento de pago. No cumple con lo que ofrece a menos que desembolses dinero por algo que no sabemos si va a funcionar o la calidad del mismo.

This app is 100% useless unless you pay for the "pro" edition, all I wanted to do was get mp3 audio and even that is behind a pay gate. Screw you Firefox for recommending this.

Can't do anything useful without money.

Recommended? Why? It refuses to work and informs you that if you aren't a PRO user then you aren't getting squat!

Unverschämte Berechtigungsforderungen. Nein Danke.
