Firefox flags MP4 file as malware

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

  • The file extension and file type are absolutely mp4.
  • There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

Yes, if a domain is flagged as a suspicious download location then all files downloaded from this location will be flagged, so this has nothing to do with the file extension. See also the about:url-classifier page.
