Sergey, please be careful. You are only supposed to get nsIDOMHTMLDocument
for HTML documents, but that doesn't have any relation to http. We load HTML
documents from http:, https:, file:, data:, chrome: and any number of other
URI schemes. What really matters is the MIME type, not the URI scheme.

mads, you haven't really answered the question about what kind of document
you're loading. Only HTML documents will QueryInterface to
nsIDOMHTMLDocument. Other types of documents such as XML and XUL do not
implement nsIDOMHTMLDocument.
