Should you be invalidating this so fast?  Both IE and Chrome handle it as expected and show the download dialog.  Firefox is the only browser that tries to render it.

i marked this report incvalid because the technical details are clear. Based on the http headers i expect that a browser renders this as text if it folows the RFC.
I made this example 7+ years ago for bugzilla: http://mversen.de/mozilla/text/mozilla.rar
This is my file on my server and this should render in the browser as text. A browser that presents a download dialog is wrong.

This bug report is invalid unless Mozilla decides to violate the rfc and do content sniffing like IE and Chrome

Thank you for detailed info.

the workaround (that i think you already know) is to right click and select "save link as". The real fix would be to change the server config to send this with a proper mime type
