Flash video does not work unless the width and height parameters are present.

I have HTML code that displays a flash video using the "object" tag.

When the tag has the width and height parameters, the video plays.

However, when those parameters are missing, the video does NOT play.

In IE, Chrome and Safari, the video plays without those parameters having to be specified. Only Firefox seems to "require" them.

Seems like the flash video should play with or without the size parameters.

The DOM Inspector shows a height:0 and width:0 with that code , so that video is hidden.

If you use an object without a classid like you posted then you do not need the embed code that you posted.
The object code with a type and data is sufficient for Firefox and should work in all browsers.
