Thanks to Mozillas proactive efforts to bring an open crossbrowser extension system means that all i had to do was copy my original Chrome plugin Code which was at version 1.2 and build an XPI from that. That was it, I didnt have to change one line of code.
If you are interested in developing the Extension further you can check them out on GitHub.
