Firefox opens things in Opus OK here, with the latest Firefox and Opus (12.29).

Make sure Opus [isn't running elevated](https://resource.dopus.com/t/why-not-to-run-opus-as-administrator-under-uac/9102/1). Other than that, if no other software (not even antivirus etc.) has been installed then I don't have any ideas as that's the same setup as my test machine.
