Claims to be something it is not. States you can use it to download MP3s, but you can't actually do that. Not unless you pay for a Pro Membership. Not worth your time is the main features of the addon can't be used unless you pay.

This is an amazing tool and the customer service for support is great

When I found this it was a GREAT day.
Works quite well and I love it.
Easy to use as well----Assome

Looks like a lot of fake 5 star reviews.

Actually it is one of the best and easiest downloader/converters I have tried...I would recommend it highly, I have used quite a few different ones..it is well worth the minimal cost involved...

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.

1080p indirmiyor.

This program is the most stable you-tube downloader you can get and I highly recommend it, but give some love (money) for the developers and you will have direct access to higher quality HD downloads which is important for various keeper videos from people's websites that encourage downloads of their videos.

Do not purchase the "pro" version of this extension. I did so and have received none of the extra functionality advertised. I submitted a support request, but this has been completely ignored and I have had zero response. Quite obviously a scam.
