I love that you can download and unlimited skip, but there is a definite learning curve. First, I didn't know I had to play the song in the tab that opens when you hit 'download' until it finishes loading, then download and keep the tab open until its done. I got a lot of partial files before I caught on. Then, I realised after saving a dozen more as .mp3, that I shouldn't have typed in a file extension, despite the save window having a blank in the 'file format' field (it will apparently automatically save things as mp4). There is also no way to create new stations through the app, you have to open Pandora in a tab to do so, and they don't 'take' until you restart firefox. So, overall, I would say better user friendliness/tutorial or labelling would make this a 5 star add-on. Now that I know how to use it, I'm good; but I would have liked to learn before I had like twenty files that are confused as to their identity. EDIT MAY 2018: I have to take this 4 star down to 1 because recently the add on started displaying a glitch that means it no longer accepts my login information, and I haven't found a clear solution to this--the only solution I found was all technical jargon with no clear steps on how to solve it. Additionally, and this has always been a problem, I really wish there was an easier way to switch off its bandwidth-hogging tendencies than disabling the add-on every time I'm done listening to the radio.
