Alice, could you try again with the latest nightly. It looks like it's fixed. At least on my side, I don't get any hang. With FF17, I got an error during printing (with MS XPS Printer) but it's normal now in FF20.

WFM too. http://hg.mozilla.org/mozilla-central/rev/21195f52311c Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20121220 Firefox/20.0 ID:20121220030912
