Boas,
De facto, se sem a mula consegues...é estranho.
Fiz uma pesquisa no "Google" e eis o que encontrei :
QUOTE("For Mozilla 1.7/Firefox 0.9 and up")
NOTE: Mozex doesn't work anymore with these new versions. There is an alternate method that works with both of them:
1. Remove Mozex (if it was already installed)
2. Write "about:config" in the browser address bar and hit enter
3. A configuration list will be shown. Right click on the list, select "New", then "Boolean"; write "network.protocol-handler.external.ed2k" as Preference Name and "true" as Value.
4. Again, right click, select "New" and "String"; write "network.protocol-handler.app.ed2k" as Preference Name and "C:\Program Files\Mozilla Firefox\firefox.exe" (or the path where the program is installed in your system) as Value.
QUOTE("For Mozilla 1.6/Firefox 0.8 and bellow")
Go to Mozex and install the last plugin release. Restart Mozilla and go to Edit -> Preferences -> Mozex -> ED2K and set it to "C:\Program Files\Mozilla\mozilla.exe %r" (or the path where the program is installed in your system). In Firefox 0.8 you will have to go to "Edit -> Preferences -> Extensions -> Mozex -> Options -> ED2K".
