Firefox and magnet

[Georgi Kourtev]

I was trying to download a file through a magnet link.  It works on my other 
machine but on a new installation of 12.04 (4.8.3) I have the following pop-up 
in Firefox: 

	"Firefox doesn't know how to open this address, because the protocol 
(magnet) isn't associated with any program."

Didn't find anything meaningful while googling. Any ideas?  I am using 
KTorroent as a client.

Thanks,
gk
