Rated 4 out of 5 stars
Downloads YouTube video and audio very simply; I used to use the in-page links it added to the YouTube page, but haven't seen those lately - may have been removed in favor of the Toolbar button, which gives all options. Sometimes have to refresh the page when I've clicked on another video in the same page instead of opening a new tab, because the button menu won't automatically update to the current video. My security program doesn't like how much it calls other resources, (ffmpeg, mp3enc...) but once authorized, it saves the files just fine.This review is for a previous version of the add-on (126.96.36.199-signed.1-signed).
The inline links can be added back from the tools menu. Go to Tools (Alt-T) Youtube MP3 Podcaster -> Options and uncheck "Hide controls on youtube.com". :).
We're working the refresh issue. It's cropping up more with the new changes to youtube :P
