At Skyfire, we have the helper dialog throw an exception (deliberately). We also suppress opening new tabs. Unfortunately, these two circumstances combine, when a new tab opens to download something, to close the Firefox window we rely on. I'm filing this bug about the failure to check rv - though the window closing underneath us may be a different bug. (Found on Mozilla 1.8 code, but the code hasn't changed in 1.9.1 trunk.)
