Steps to reproduce:

In Javascript:
1. Create an object containing a key that is a number and with any value.

3. Run script and in console, click the object representation, e.g. `Object { 11: "monkey" }`.

JSFiddle reproducing the bug: https://jsfiddle.net/Beppe/Ldo8p9mb/. I could reproduce this using a new profile.


Actual results:

No key/value is shown:
{…}
__proto__: Object { … }


Expected results:

Key/value is shown:
{…}
11: "monkey"
__proto__: Object { … }

Hello sebastian, thanks for reporting !
This looks like Bug 1371936, which have been fixed a few days ago. I just checked in Nightly and the objects logged in the page do contain the numeric indices (by the way, do you know you can use `console.dir({11: "monkeys"})` to autoexpand objects ?). 

I will proceed and close this bug, but feel free to re-open it if you still see some weirdness with Nightly :)
