I'm a radio broadcaster who gets much of my music for broadcast from artist sites. These are legitimate downloads because artists freely post their music for me, and others in their net communities. Download Helper normally works on Bandcamp, SoundCloud and other streaming sites, but completely ceased working as of this week. The Download Helper icon spins and the song is displayed (although not always), and when I choose to download it, a number appears next to the icon (indicating a download is in progress), but nothing happens (no download ever happens). A check reveals the download que remains empty.

My FireFox version is 36.0.1 and OS is WinXP. Please help ASAP!
