Hi Govind,
To perform web testing with Firefox, the "Web Testing", "Firefox Support" and "Web Checkpoints" plug-ins should be installed (see the
Web Testing - Required Plug-Ins help topic). Please make sure that the plug-ins are installed.
If they are, please give us some additional information:
1. Do you face the issue when trying to access the object in Internet Explorer?
2. Can you reproduce the behavior with any page or only with the exact one? For example, you can try recording a simple test with the google.com page. Providing us with access to your page would be of great help too.
