I have created an firefox extension(.xpi) using gecko 13 sdk. That works perfectly fine on Windows XP but its failing to register itself on Vista and Win7. On Win7 and Vista, I am getting error "Obj is undefined" while executing this line in my js file

Obj = Components.classes[classid].createInstance().

I have tried launching firefox as administrator but that didn't help. Also, when I enabled NSPRLogging then I got this error.


0[f0f140]: nsNativeModuleLoader::Init()

Kindly guide me how I can make this extension work on Vista and Win7.
