Hi Michael,

Thank you for bringing this issue to our attention. We investigated it and here are our findings:

The problem does not exist if UpdatePanel is not used.
The setup works under IE in all cases.
Ultimately the reason for the problem is in the Firefox implementation. It can be reproduced if no RadControls are used as well.

Here is a sample setup that reproduces the problem without RadFormDecorator - it actually represents how the RadFormDecorator works. When you click a "decorated" button, RadFormDecorator finds the corresponding real button and call its click() method:

    
            <asp:ScriptManager ID="ScriptManager1" runat="server"> 
        
            </asp:ScriptManager> 
        
            <asp:UpdatePanel ID="panel1" runat="server"> 
        
                <ContentTemplate> 
        
                    <script type="text/javascript"> 
        
                        function submitForm() 
        
                        { 
        
                            var input = $get("<%=Button1.ClientID %>");                 
        
                            input.click(); 
        
                        } 
        
                    </script> 
        
                    <button onclick="submitForm();return false;"> 
        
                        Click to submit</button> 
        
                    <asp:Button ID="Button1" runat="server" Text="test" OnClick="Button1_Click" /><asp:Label 
        
                        ID="lbl1" runat="server"></asp:Label> 
        
                </ContentTemplate> 
        
            </asp:UpdatePanel>

The good news is that there is an easy solution for this case - you only need to set the button's UseSubmitBehavior property to false (it is true by default). Then the button will be rendered as <input type="button" .. element and everything will work as expected.
