Error.stack is what you need. It works in Chrome and Firefox. For example

try { var a = {}; a.debug(); } catch(ex) {console.log(ex.stack)}

will give in Chrome:

TypeError: Object #<Object> has no method 'debug'
    at eval at <anonymous> (unknown source)
    at eval (native)
    at Object._evaluateOn (unknown source)
    at Object._evaluateAndWrap (unknown source)
    at Object.evaluate (unknown source)

and in Firefox:

@http://www.google.com.ua/:87 _firebugEvalEvent([object Event])

There is a library called stacktrace.js that gives you cross browser stack traces. You can use it simply by including the script and calling at any point:

var trace = printStackTrace();
