It's great! If you ever used the RSS Livemarks feed from Firefox, this is it, broken out as an extension. I only wish they add a UI for .mp3 media (i.e. podcasts) so they would look and play nicely on the livemarks page. Currently when I click the mp3 link in the RSS page, the firefox mp3 UI shows up and since it is streaming, it breaks on some sites. Most site will limit then number of connection and since the FF browser go back after playing a small chunk to download the next chunk, it timesout and doesn't play past 10 minutes.
