Great addon, but recently downloading has become hit or miss. Sometimes the 'save as' window will pop up, other times it just sits there & does nothing. I tried downloading with other addons, and they worked OK, so there's a bug in there somewhere. Hopefully it gets straightened out.

While yes, we can download videos, we cannot download mp3.

You have to "donate" so you can download mp4s and videos in 1080p

constantly failing.

All too often the downloaded video will be of 0 bytes; failure rate can range from 20% to 100% (in 10 videos).
At times when other addons didn't work, this generally did, but it fails so often now that it can't be relied upon, so I can't recommend it currently

MP3 Downloads nur als Premium möglich

only works for free on "popular videos."

very limited video quality for download (currently the advertised 720p is also removed, so only 360p download is available), as means to push for pro version. I am disgusted by this type of abuse to the community. It felt more akin to a scam than an honest add-on

Does not work
