Firefox 35 was released today. You are 6 versions behind right now! You can use Help > About Firefox to check for updates and install the latest version.

Firefox goes by the MIME-Type that is sent with the file. That change was probably made on the server where those files came from. If you can provide a URL to the webpage where you download those files from someone here can look into the source of that problem more thoroughly.
