I'm trying to bulk download some mp3's of a podcast, and firefox is merrily trying to play them in the browser. Right clicking/save as for all of the episodes I need to catch up on would be a bit of a pain, and frankly if I encounter an MP3 I'm more than likely going to be downloading it for later listening. I found some previous similar questions, and the chosen answer was the about:config setting media.play-stand-alone. This, however, also makes the browser default to downloading webm files, rather than watching in the browser. I actually prefer watching them in browser since most I encounter are short <1 min clips. Short: I want mp3 and other audio to be treated as a download, asking me where to save it and whatnot, but webm and other compatible video to go ahead and play in the browser by default. Is this doable? Running firefox v 50.
