Now that we know this is working as designed, I'll point out that a
Firebug extension can add new rules for formatting objects. For
example there could be a jquery extension that formats the result of
jQuery() in nice ways. The extension would create a 'Firebug.Rep',
requiring an object identification method "supportsObject" that
returns true if the argument is handled by the 'rep' and a domplate
'tag' to define the output. The Firebug.Rep is registered with Firebug
and that's it. The hard part is the domplate, see

In 1.4a12 I get
>>>({splice:[].splice, length:2, '0':0, '1':1, '2':2})

Object length=2
and:
typeof ({splice:[].splice, length:2, '0':0, '1':1, '2':2}).splice === 'function'
is of course true.

Re: firebug regression: console.log(jQuery('div')) less useful
It may have been deliberate to 'duck type' or allow Array-like
objects. An instanceof test would be the only accurate test, but it
may (or may not) be helpful to handle user-created objects as Arrays,
or other things like NodeList, which seems to have its own special
handling.

Re: firebug regression: console.log(jQuery('div')) less useful
Which explains why the Object is not being taken as an Array.
typeof obj.splice === 'function'
that condition is failing. Correctly too an object is not an Array.

Re: firebug regression: console.log(jQuery('div')) less useful
That's not an Array it's an object. For a native Array length is controlled
for you and splice() is provided to you.
[] === Array
{} === Object

Using Firebug 1.2.1, an object with properties |length| and |splice|
is not formatted the same as an Array.
Example:
>>> ({splice:1, length:2, '0':0, '1':1, '2':2})
Object splice=1 length=2
>>> [0,1,2]
0,1,2
Please describe how an array is to be formatted so that a bug can be filed.

Re: firebug regression: console.log(jQuery('div')) less useful
Any Javascript object with 'length' and 'splice' should format as an
array. If not please report a bug.

Re: firebug regression: console.log(jQuery('div')) less useful
Thanks; that makes sense. But Firebug also changed the way it displays
true arrays. Arrays of simple types like [1,2,3] are listed; arrays
that contain objects are displayed as "Object". console.dir() helps,
but it was nice to have it all in one line.

Re: firebug regression: console.log(jQuery('div')) less useful
jQuery('div') is not an array. It has length but not splice. So
Firebug does not format it as an array.
In Javascript, the line between what is an array and what is not an
array is unclear. After many versions the current test in Firebug
requires an array to have 'length' and 'splice'. Earlier versions of
Firebug only required 'length', but that caused some objects to be
formatted as arrays that did not have numerical indexes.
