FYI, unlike bug 649857, this doesn't seem to work in 3.6.16 either. You get about the same error:
uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: chrome://exampleext/content/firebugwrapperexample.fromjohn.html :: anonymous :: line 11" data: no]

I don't know what this bug is about. When I add the testcase here to a chrome mochitest, I don't get an exception on line 11 and everything seems to Just Work (TM). There are a couple of cases here where it seems like the testcase wants to use cwu instead of cw, but those cases work for me either way. Am I missing anything?
