Rated 1 out of 5 stars

I tried downloading several tracks from youtube, and watched disappointed as the plugin spit out several different file sizes- first 8mb, then 21mb, then 47mb (repeat attempts) for a 103mb file.

No good!

This review is for a previous version of the add-on (2.7.1.1-signed). 

Hi, There's a known issue where closing the tab while downloading stops the MP3 from being created. In 2.7.1 don't close the tab. You can get 2.7.2 on www.glimmersoft.com. It should be up on mozilla.org soon too. Thanks!
