I decided after having issues with Twitch again today to give this addon a try. Now I remember that I've tried this addon before for Firefox and I wish I could say that I could give this more than a 1-star but it doesn't work. I've tried figuring it out to be sure it wasn't me and I checked the other reviews here, but other folks seem to have problems getting this addon to function and play a live Twitch stream. To the author of the addon, if this addon worked once before, it sadly did not work for me more than a year ago and doesn't work now.
