It gets an extra star simply for being able to find audio on sites that other add-ons fail to find any. That's the end of good things to say for me though.

This thing took over 10 minutes to encode a podcast on my 3950x 16 core CPU and locked up firefox *hard* the whole time it was doing it. That javascript lame implementation is just plain *horrendous*. Please just rework this thing into an audio downloader and let me encode things if I actually need to using real software.
