Hi Saifi! Though I am extremely unknowledgeable in Javascript or for that matter anything related to web development, I once came across this thing called Aptana Jaxer. Here is the website - http://www.aptana.com/jaxer. It said it is a 'Mozilla-based application' and hence I read more about it. I have no other understanding of it any further.
I'm sorry if I've diverted you to the wrong direction. Regards, -- Navneet
