Try in another browser too, such as Safari or Chrome.

If it works only in IE, it's probably the Flash Cookie Bug the other answers mention.

If it works in everything except Firefox, it could be that there's no css defined for the progress bar. I don't know why this causes a problem, but I found that it did. As soon as I put the sample styles into my css file, it started working in Firefox.

The css I used is as follows:

DIV.ProgressBar { width: 100px; padding: 0; border: 1px solid black; margin-right: 1em; height:.75em; margin-left:1em; display:-moz-inline-stack; display:inline-block; zoom:1; *display:inline; }
DIV.ProgressBar DIV { background-color: Green; font-size: 1pt; height:100%; float:left; }
SPAN.asyncUploader OBJECT { position: relative; top: 5px; left: 10px; }
