Mozilla/Emacs merger?

[Peter Wayner]

Hey--

I was recently working with my browser and wishing that I could write 
Emacs-like code to operate upon the HTML being displayed. It doesn't 
have to be lisp. It might just be JavaScript. But does anyone know of 
any projects to build a browser that gives the user the ability to 
execute code on the HTML on display?

Thanks,

Peter
