I have created a very simple page with a button and the ajax compnents. When I click the button, the update panel doesn't display in firefox but it does in IE. I took this from one of the examples. Is there something unique to Firefox? The example works on the demo page, but when I remove the content code and place it on my page, it doesn't.

Thanks

No change. I tried creating one one my own first, fyi. It didn't work, which is when I copied from the demo page. Could you supply a simple example? I did this real quick. It works in IE, not FireFox.
