Rated 5 out of 5 stars

The first time I installed, it did not work. I removed it, restarted and reinstalled. Now it works quickly and without complication.
I also see that it can do longer downloads (like 1:20:00)

Sometimes I get an annoying animated GIF and it adds an unnecessary icon to my address bar. Those are my biggest complaints.

This review is for a previous version of the add-on (2.6.2.1-signed). 

If you haven't already please uninstall and reinstall the plugin from Tools -> Add Ons. If it still does not work Turn on debugging as described on http://www.glimmersoft.com/podcaster/help.html, try a few downloads, then turn off debuging and send me the file "youtubeMP3Podcaster.trel.sqlite" from your extensions folder. See this page:

on how to find the profile folder where you'll find that file.
