Rated 1 out of 5 stars

'Click the Download button below to start downloading the mp3 in a new window. Upgrade to for faster, cleaner and ad-free downloads without this manual button click.' .......this is what pops up when you use this extension. Firefox needs to have a zero stars rating for deceptive add-ons like this.

This review is for a previous version of the add-on (7.24.1-signed). 

One more click "ONLY" for MP3 download option which requires powerful servers to do online conversion which cost money and this becomes deceptive ?

I guess you realize money does not grow on trees and hosting companies do not offer powerful/servers and bandwidth for free???
