The latest Firefox 3.5 release now support HTML 5 open video format. This means videos and movies can be dynamically played and rendered on the Firefox 3.5 browser without the use Javascript players and plugins. A typical video format syntax would look like this:

<video src=”out.ogv” autoplay>
Your browser does not support the <code>video</code> element.
</video>

The first line tells the browser it’s a video element with a source file of out.ogv. The second line is for browsers that do not support HTML 5 video element. The third line is the closing of the video element.

If you are seeing “Your browser does not support video element,” it means your browser does not support HTML 5 video format. You can try using Firefox 3.5 to view the video.

For developers and web designers, you can try using Flash as an alternate if the video element is not supported using the following format:

<video src=”video.ogv” controls>
<object data=”flvplayer.swf” type=”application/x-shockwave-flash”>
<param value=”flvplayer.swf” name=”movie”/>
</object>
</video>
