This is the byte count reported in the "opening" dialog.

In particular, I see it with a PHP script that dynamically generates files, and yes, these files contain data.

I see this a lot now in Firefox 8 but do not recall such in earlier versions.

It happens when server response with no Content-Length: field. "Transfer-Encoding: chunked" provides option to download a attached file without known file size.

POST /tmp/Control/form HTTP/1.1

HTTP/1.1 200 OK

Content-disposition: attachment; filename=ClientFile.exe

It is known problem. See https://bugzilla.mozilla.org/show_bug.cgi?id=683258

Thank you for the info, especially the bug report. It seems to be more or less fixed in Firefox 9 (beta). It simply doesn't show any size now if unknown.
