Other download actions can be set from the Opening file dialog box that opens when you first encounter a particlar file type (see above). This section applies to all Firefox versions since Firefox 3 and SeaMonkey 2įirefox and SeaMonkey will use an installed and enabled plugin to open a downloaded file by default, based on its MIME type (see Issues related to plugins for more information). You can use the 'Browse' button or click the drop-down menu icon and then click on 'Other' to open a 'Choose Helper Application' dialog, as shown here on Windows. You can choose to open the file with that application or you can choose or browse to a different application. The 'Open with' option can show a 'Choose' or 'Browse' button, if no application is associated with the file type (shown here on Windows), or it may show a default application for the file type.

Starting in Firefox 3 and SeaMonkey 2, the 'Opening ' dialog will also appear if you have selected 'Always ask' as the action for the file's content type in your (Helper) Applications options/preferences ( see below). If you see an 'Opening ' dialog asking if you want to save the file or open it with a specified application, that normally means that your Mozilla application cannot handle the MIME type internally, no plugin is installed and enabled that can handle it and you have not previously selected a download action or helper application to always use for that type of file. When you click a link to download a file, the MIME type determines what action is taken.
