Hi Fayed, If I understand correctly, the Desktop Application (Web Apps) feature you are talking about is a feature of Ubuntu and not related to Firefox. We only offer support for Firefox and Mozilla software in these forums. However, I found a [http://askubuntu.com/questions/166655/how-do-i-remove-a-website-from-ubuntus-web-applications thread on another forum] that may have the solution for you. In the future, you can also check the [http://ubuntuforums.org/ Ubuntu Forums] for help on issues related to it. Thanks!! - Ralph

Thanks alot, Ralph :)
