(Firefox :: File Handling, defect, P5)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170518000419

Steps to reproduce:

Download a .ova file such as:

I am on macOS Sierra running latest stable.

Actual results:

Extension is immediately renamed to .ovf (first with .part, then .ovf after finished).

Expected results:

File extension should not be renamed to a related but incompatible file extension. How this happened is beyond me. Too similar to be a coincidence, yet very weird. Chrome and Safari on mac do not have this problem.

WFM with FF53 on Win 7. I think it's related to the file association on your OS.
This may happen if the server sends a Content-Type header that is locally associated to "ovf" but does not have "ova" as an additional valid extension for the same MIME type.

Can you try to locate the "mimeTypes.rdf" file in your Firefox profile folder, rename it to something else while Firefox is not running, then see if the problem still occurs?

Since upgrading to FF54, the problem went away.
