If you select Always Open Similar Files in the Downloads panel right-click context menu for the file, ( see below) a new Content Type and Action entry will be added to the General panel Applications section of Firefox settings. If Firefox does not have a set download action for a type of file, Firefox will save the file by default. (If you use an add-on and need help with it, you should visit the add-on site or contact the add-on developer for support.) You can contact the website in such cases, or you can try a Firefox add-on such as Content-Type Fixer to work around the problem. To learn more, see Properly configuring server MIME types and Common MIME types at MDN web docs. For example, Firefox may display the content as plain text instead of opening the file in an application. When you click on a link to download a file, the Media type, also called the MIME type or Content type, as configured by the web server, will determine what action Firefox will take.įirefox will not be able to properly handle a file if a misconfigured web server sends it with an incorrect content type.
