I am not able to associate magnet protocol in FF. I am using Ubuntu 11.10 with FF 10.0.2. Created the following in about:config and restarted FF, but still getting the below message.
Boolean Name: network.protocol-handler.external.magnet -> Value -> true String Name: network.protocol-handler.app.magnet -> Value -> /usr/bin/transmission-gtk
Chrome was able to recognize the magnet, so was able to get it work.
But, still interested in how to get it work in Firefox.
