Viewing multimedia files in Firefox 3.0 requires a plugin (like Flash). Firefox 3.5 can play Vorbis audio and Theora video (which both use the Ogg container format) files without a plugin (formats developed by the The Xiph.Org Foundation, which are free to use without patent restrictions.)

To view Vorbis audio and Theora video files in Firefox, upgrade to the latest version of Firefox. For instructions, see Update Firefox to the latest version.

In Firefox 3.5 and above, you can play some types of sound and video files on web pages without a plugin.

What is open media?

Because the use of many audio and video file types is restricted by patents, a third-party application called a plugin is required to use them. A plugin (such as Flash) is a small application that runs inside the browser window.

However, Vorbis audio and Theora video file types (developed by The Xiph.Org Foundation) are free to use without patent restrictions, and can be viewed in Firefox without a plugin. Vorbis and Theora both use the Ogg container format, and are both sometimes called "ogg."

A sample Theora video file is available - Meet Firefox 3.6.

Audio and video controls

When you visit a website that includes a Vorbis sound file or a Theora video file, you will see controls for managing playback when you hold the mouse pointer over the media on the page.
