Steps to reproduce:

In middle of rendering a page, the server generates dynamic content and delivers to browser line by line.  Call to fflush used to cause new content to appear in browser, but now the page must be complete and the connection closed before the browser renders the content.  Server is boa with custom cgi.  This is new to this version of Firefox.. used to work fine.  Works on older versions as IE, chrome, etc.

Can you post the URL to the server, or is it internal?

Internal.. it runs on an embedded box.  The CGI is implemented in C and as I mention, calls to fflush(stdout) used to cause the browser to render the partial content.  This is needed because this is the response page from setting the box's IP address and explanatory text and a link to the new IP address are output to be browser *before* the IP is actually changed.. since that will leave the browser in no-mans' land.

This is still a real issue in Firefox 10.0.1: fflush before the page is completely output does NOT work.

In one case, I believe this is be related to outputing javascript to set window.location and then calling fflush with no results.  Sequence of server output:
- content type, header
- formatted content
- <script language=javascript> window.location='...'; </script>
- run local shell script and wait for completion; takes about three minutes
The window.location page has dynamic javascript to read and display a log file as it is generated by the shell script.

The implementation can be changed to accommodate this behavior, but this behavior in the browser used to work.
We are unable to do something without a testcase
