Comment 10 for bug 229040

The fix in Launchpad sets the content type of new .debdiff uploads to text/plain, because seb128 discovered that Firefox does not display text/x-diff (which is probably the more appropriate choice of content type for debdiff output) in-browser. Even once /etc/mime.types has been updated (assuming text/x-diff is chosen), we'll keep the text/plain behaviour until Firefox displays text/x-diff in-browser by default, or until it becomes easier (or possible? I couldn't figure out how to change the default) to get Firefox to display it in-browser.
