I've always felt that firebug has been a little bit better than the chrome developer tools. Now I might reconsider and start using chrome for development instead. The ability to add new css rules in the element view something I've been dreaming about for a long time. The ability to write more than one line of javascript without enabling a different mode is also absolutely fantastic. Is there a similar list for firebug? A strong advantage of firebug is of course that it's has a bunch of nifty extensions. Which one do you prefer?
