I'd like to put the button on the stausbar of my Firefox Nightly 22. I always put it on the statusbar, but It always moves back to the addressbar... maybe cause new versions of Firefox doesn't have statusbar?
Warning, this is NOT high quality! Instead of simply downloading the mp3, it links to a site that downloads the mp3, then re-encodes it to a NEW low quality mp3 file!?
I don't understand why there are addons that re-convert a YouTube mp3 into a new mp3? Re-encoding a lossy file is just plain dumb as you inevitably lose quality. But to re-encode at the low quality of 128kbps (as this site does) is just crazy.
Currently the best way I've found to download mp3 from YouTube is to use an addon called "Download YouTube Videos as MP4". You can then extract the mp3s with an excellent program called "Free video to mp3 converter".
