ECMAScript.next features in Firefox?

Is there a list somewhere of ECMAScript.next features that have already been implemented in Firefox?

Thanks!

Do we have a similar list for the features in chromium that are enabled
through the harmony flag? (  http://codereview.chromium.org/9008031 )

Paul Irish did a code search for that:

To elaborate, the --harmony flag currently activates the following
experimental features for V8:

- block scoping, let, const, block functions
(http://wiki.ecmascript.org/doku.php?id=harmony:block_scoped_bindings,
etc)
- proxies, though not direct proxies yet (i.e.,
http://wiki.ecmascript.org/doku.php?id=harmony:proxies)
- maps and sets
(http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets)
- weak maps (http://wiki.ecmascript.org/doku.php?id=harmony:weak_maps)
- typeof null reform
(http://wiki.ecmascript.org/doku.php?id=harmony:typeof_null)

On the browser side, that should become functional in Chrome 17 (some
of it is in 16 already, but incomplete/buggy) by setting
--js-flags="--harmony". If you are on the Chrome dev channel, you
should also see it show up on chrome://flags soon.
