This document explains all of the {for win}options{/for}{for mac,linux}preferences{/for} available in the Applications panel of the {for win}Options{/for}{for mac,linux}Preferences{/for} window of Mozilla Firefox. To access the {for win}Options{/for}{for mac,linux}Preferences{/for} window, [[T:optionspreferences]] For other panels, see [[Options window|{for win}Options{/for}{for mac,linux}Preferences{/for} window]]. The {menu Applications} panel lets you choose how Firefox [[Managing file types|handles different types of files]], such as PDF documents or MP3 audio clips. For each content type Firefox recognizes, you may select an action: open the file in the Firefox window with a plugin, open the file with an application on your computer, or save the file to your downloads folder. Some file types, like [[Glossary#live_bookmark|Live Bookmark]] feeds also allow you to select a web application. {for win}[[Image:50803044dc874239dc4be66462170c40-1258704216-933-3.png]]{/for}{for mac}[[Image:50803044dc874239dc4be66462170c40-1260032544-474-1.png]]{/for}{for linux}[[Image:50803044dc874239dc4be66462170c40-1258704216-933-1.jpg]]{/for} To change how Firefox handles a file type in the list, click on its name to select it. The drop-down menu that appears will allow you to choose actions for that type of file: * '''Choose an application''': To choose a local or web application to handle a type, select the application from the drop-down menu. If you want a local application that is not in the menu to handle the type, select '''Use other...''' from the drop-down menu and point Firefox to its location. * '''Choose a feature or plugin''': If you want a feature or a plugin in Firefox to handle the type, and one is available, select it from the drop-down menu. * '''Save on your computer''': Some file types can be saved to your computer. Select '''Save File''' from the menu for one of these file types to have Firefox save that type of file to the location specified in the {menu General} panel ({menu Main} panel in Firefox 3.5) of the {for mac,linux}[[Options window - General panel#Downloads|Preferences window]]{/for}{for win}[[Options window - General panel#Downloads|Options window]]{/for}. {note}'''Note:''' When a plugin is available to handle a type, and you choose another handler to handle that type, Firefox will only use your chosen handler when you access the type directly. When the type is embedded inside a web page, Firefox will continue to use the plugin to handle the type.{/note} {note}'''Note:''' The Applications panel has limited functionality for editing. You can change the action for an existing file type but you cannot add or remove file types. Entries are added automatically when you download files and select actions for them. You may get problems if you download a file that is labelled with the wrong MIME type. There is no way to identify or delete a bad entry in the list. If this happens you may need to look at the file {filepath mimeTypes.rdf } &nbsp;in your Firefox profile.{/note} = Adding a download action = See [[Managing file types|#Adding download actions]]. <br/> <br/> ::[[[[Options window Back to {for win}Option{/for}{for mac,linux}Preference{/for} window article]]]::
