I'm trying out some YouTube-to-MP3 converter addons for firefox to find something that fits my needs. And even though this addon is VERY easy to use, it still saves MP3's as 128kbps. That is not enough for me. 192kbps is to what expect AT LEAST on todays internet.
Once again: I would recommend this addon to anyone who isn't so picky about mp3 quality as I am. It's very easy to use.
