Thanks Axel, that seems to work in both xpcshells. In both cases it returns:

[xpconnect wrapped nsIDOMSerializer]

It also works from my Firefox Javascript window, and returns:

[object XMLSerializer]

But it doesn't work from the Thunderbird Javascript window. This one 
returns:

Error: Components.classes['@mozilla.org/xmlextras/xmlserializer;1'] has 
no properties

Does this mean I'm missing the bit that maps nsIDOMSerializer to the 
name XMLSerializer? If so, how do I go about installing that? All I have 
done so far is to copy the files run regxpcom...
