Hi all,

When I install firefox extension from
http://simile.mit.edu/repository/java-firefox-extension/ 

But when I install java-firefox-extension-2.0.0.xpi then restart firefox ,

It's shown me the msg as follows :

 

 

Error calling method on NPObject! [plugin exception:
java.lang.IllegalArgumentException: 

No method found matching name newInstance and arguments
[com.sun.java.browser.plugin2.liveconnect.v1.JavaNameSpace,
java.lang.Integer]].

 

 

 

Any help will be appreciated !

 

 

Cheers,

Andrew
