Yippee!!! Other than this addon, I wonder if there are any other download manager that do the same.

Running F@H would be more energy-efficent while doing medical research some good.
OT: What ports are used by F@H? Mine can't seem to download the cores automatically. I have forwarded Port 8080 but using a port checker shows otherwise. I have managed to forward other ports with similar settings though.
