Description

Probably, the reason is #17207 (Testing navigator.mimeTypes for known names can reveal info and increase fingerprinting risk).

Try to open that link in Tor Browser. Problem seems to be with second instance of firefox.exe (not #17207).

I get a save dialog because the server sends a Content-Disposition: attachment header. This header forces Tor Browser to display the save dialog instead of showing the content in the browser.
