But of course, and is what I do.

Sure, but that won't work for people like me, who need to modify the DOM
after the transformation.

No error, and my pref are set to show everything.

It is, sort of. It is a limitation for when the target document is
'about:blank', but I can use it now (after I removed the first text
(rss/rdf) element/node from the source document). Good enough for testing.

Sorry no testcase here; but I am trying to add a new content handler to
intercept loads of "application/blob-xml" and load/translate the blob
document with XSLT into XHTML which should be opened in a new or unused
(about:blank) tab.
I'm still stuck with some DOM/network issues, but I think that I better
ask these questions in the respected newsgroup.
