Firefox can handle many types of files. However, for some files such as movies or music, Firefox needs Plugins or external applications that can handle those files. If Firefox doesn't have the needed Plugin or doesn't know what application to use to open the file, it can still save the file to your hard disk. When saving files, you can keep track of them using the Download Manager.
Plugins extend Firefox's functionality and run within it. Plugins like Sun Java, Adobe Flash, and RealNetworks RealPlayer allow Firefox to show multimedia files and run small applications such as movies, animations, and games. You can find common Plugins on the Plugins page at Mozilla Add-ons.
When files cannot be opened within Firefox, you can choose to open them with applications outside of Firefox. For example, you can use the media player of your choice to play MP3 files.

To open this dialog, select , open the Content panel, and click the Manage… button in the File Types section. You can change the action for a file type or remove it. More information about this dialog is available in File Types optionspreferences.

Firefox stores copies of frequently accessed pages in the cache. By doing this Firefox doesn't have to retrieve the page from the network each time you view the web page.
To set the size of the cache:
Important: A larger cache allows more data to be quickly retrieved, but more of your hard disk space is used.
When you quit Firefox, it performs cache maintenance. If maintenance takes longer than you wish, try reducing the size of the disk cache.
To reload a page at any time, click the Reload button in Firefox's Navigation Toolbar. Firefox then loads and displays the latest version of the page.
