Load EToken Certificate in ANY Browser

I am working on an applicaion which does authentication based on EToken (Specifically we are using aladdin eTokens). Previously we are using just normal (File Certificates) certificates to which were added in clients browser, and its working well with Mozilla and Internet Explorer, we are using applet to load the certificates in the browser.

Now, the problem comes with the eToken it also load the certificates when we insert the device in开发者_JAVA技巧to the machine but I am not able to load the particular certificate in Mozilla Firefox the same applet code is working fine with IE. In firefox I am getting error something like java.security.InvalidKeyException: Unsupported key type: null that says that the private/public key is null, Mozilla is not able to access the keys of the eToken Certificate.

If you got any clue please help me out.
