The attached testcase has a single line script:
document.body.appendChild();
It causes a exception which arrives in the consoleService thus:
[message]=[JavaScript Error: "uncaught exception: [Exception... "Not enough arguments" nsresult: "0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)" location: "JS frame :: http://localhost:63636/EclipseWorkspace/FireclipseTests/WebContent/UncaughtException.html :: <TOP_LEVEL> :: line 10" data: no]"];
Now this can be parsed but there does not seem to be any description of the format so I just have to guess and hope.
More, much more important there is no stack trace. An exception with out a stack trace, I thought we got past that ;-).
Reproducible: Always
Steps to Reproduce:
1.

3.
The entire test file:
----
<html>
<body>
<h1>Uncaught Exception Error Message Test</h1>
<pre>
[message]=[JavaScript Error: "uncaught exception: [Exception... "Not enough arguments" nsresult: "0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)" location: "JS frame :: http://localhost:63636/EclipseWorkspace/FireclipseTests/WebContent/UncaughtException.html :: <TOP_LEVEL> :: line 10" data: no]"];
</pre>
</body>
<script>
document.body.appendChild();
</script>
</html>

Would be nice if XPConnect created better exception objects here!

This particular testcase now displays "TypeError: Not enough arguments to Node.appendChild. @ https://bug418346.bugzilla.mozilla.org/attachment.cgi?id=304157:10".
This seems to happen thanks to the WebIDL bindings, but I'm not sure if the plan is to migrate everything over to the new bindings.

I believe the plan is to convert everything that can be used on a webpage. There will still be chrome-only stuff on old DOM bindings.
