- Insert about:config in the address bar
- Right click on the list, select New, then Boolean; insert network.protocol-handler.external.ed2k as Preference Name and true as Value
- Now another right click, select New and String; insert network.protocol-handler.app.ed2k as Preference Name and /path/to/ed2k (path to where the file is installed on your system) as Value.
For Firefox 3 and higher only, you should also:
- Right click on the list, select New, then Boolean; insert network.protocol-handler.expose.ed2k as Preference Name and false as Value
After that, click over an ed2k link, and Firefox should ask which app you want to use to open the link. Choose /usr/bin/ed2k and it should work.
Só que pra mim, o path ficou /usr/bin/ed2k
