Thank you very much glen for the help, Now, IT WORKS ! Now I really do the difference between a debug build and a release build.
Actually, I'v placed the nspr-4.6.4 libraries in c:\jss. So, I've only replaced the debug libraries of nspr-4.6.4 by the release ones and everything works properly. I didn't set my path to the nss-3.11.4 package because the libraries existing in my C:\Programe Files\Mozilla Firefox are more update (3.12.3.0).
