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. > So, only the last N number of lines are displayed. > > Type this in the about:config. > > devtools.hud.loglimit. (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. -- PointedEars FAQ: | SVN: Twitter: @PointedEars2 | ES Matrix: Please do not Cc: me. / Bitte keine Kopien per E-Mail.
