Yes, but that is not the reason for the above result.  This is:

Object.getOwnPropertyNames(document).filter(function (name) { return 
Object.getOwnPropertyDescriptor(document, name).enumerable; })
| < Array [ "location" ]

And in Chromium:

JSON.stringify(document)
| TypeError: Converting circular structure to JSON

Object.getOwnPropertyNames(document).filter(function (name) { return 
Object.getOwnPropertyDescriptor(document, name).enumerable; })
| Array[147]

The structure is “circular” in WebCore because at least “document.body” and 
“document.body.ownerDocument” (=== document) are own, enumerable properties.

In general, it is a Bad Idea to subject host objects to JSON 
stringification.

(easier with “loglimit”)

Thanks; the default for devtools.hud.loglimit.console is 200 which explains 
the observations.  Unfortunately, there appears to be no way to disable the 
limit (neither negative values nor 0 work).

The least that should be done by Mozilla is to display a notice that the log 
limit has been reached and that output is incomplete.
