Handling ED2k links in Firefox can be configured in two ways: either for an individual user, or for all users of the computer. Configuration for a single user
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 Ubuntu Lucid users, you should set the Value to just "ed2k" instead of "/usr/bin/ed2k".
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. 設置后，重啟firefox4打開電驢連接網頁，打開amule..無法關聯。。。。 find / -name ed2k 結果是：/usr/bin/ed2k路徑沒錯。修改為777許可權也不行。
