It's not functional extenstion, just banner for PRO version.

Youtube switched to separate audio/video streaming technology for higher quality formats and no longer provides direct 720p! IDIOTIC!

It's useless only allows 360p downloads and no mp3 and no HQ downloads! ..

Just does not perform as it says....useless...:(

The stupid thing doesn't work. I paid but when I try to download a video it pops up the same message about needing to be a Pro User. I'm not going to pay again!

Doesnt download 1080p videos. You must BUY the pro version.

Does nothing, unless you are willing to run Youtube’s nonfree software in your browser.

Müll funktioniert nicht !!!

you need to pay for "pro version" to download 1080p.

I used to love this addon because it was the most reliable but now I can't get it to f***ing work at all so without any bias here DON'T EVEN bother either its because firefox is a $*@#% and their reckless excessive updates that can screw with current addons that may not be supportive so yeah THIS one no longer works on my machine and statistics show it may not for probably a marginalize number of users.

cripple ware free with conditions

needs payment to use

Pro version is required

Devs tell users that "Converting these streams to downloadable formats for you needs powerful server infrastructure, therefore 1080p/mp3 downloading has been limited to PRO users".
That's absolutely not true. It's done instantly by any free video encoder. So don't lie to you users.

They charge money for HD also i only tried this because my other downloader kept failing but this wasn't able to do the job either. So, i might as well stick with the broken one that doesn't beg for money.

Garbage. Its not downloading MP3 or HD unless you pay for it.

fonctionne pas. faut payer.....

Its useless.

it dosent work anymore

Doesn't do as advertised. Doesn't work with Youtube's new bullshit. The only way this works is if you have your own video editing software and download the video and mp3 separately and then manually combine and render them.
