Redirecting f? to karlt as bsmedberg suggests. Updated patch with SIGQUIT handling as well.
I left SIGINT doing a eForceQuit; from comments in this bug, it sounds like people start firefox from the command line and then C-c it. For those sorts of usecases, it would be annoying to click a dialog. (Firefox should just save the data always, without asking, but that's a separate discussion.)
