I've seen it already.It was my first google search, but I don't think it is the same problem. This issue shows only question mark, but I got both size and question mark :(

Yes, the question mark is displayed in cases where Firebug couldn't figure out the size of the response (e.g. missing Content-Length header). This is considered rather as a bug and should be fixed in the combo: Firefox 3.6 + Firebug 1.5 Honza
