From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; 0.8.1) Gecko/20010323 BuildID: 2001032319 The message says: "This file has mime type text/xml and cannot be viewed using Mozilla. ..." But Mozilla can view files with this mime type. Something else has gone wrong. Reproducible: Always Steps to Reproduce: 1. Open http://www.hipnt.com/MathML/smallsampleout.xml 2. Read the error message. Actual Results: Mozilla refuses to open the URL. Expected Results: A. Post a more meaningful error message. B. You could actually open the stream as XML (since the extension is xml), but that might be risky. Note that I will probably change the server www.hipnt.com so that is serves XML files as text/xml in the near future. But it's easy enough to change your own server to reproduce the bug.
Yeah... This was a "good idea" someone had that got implemented kinda poorly.. *** This bug has been marked as a duplicate of 74510 ***
