I have asp:menu control on my page. Never had any problems with it, until my Firefox was updated to v17.  

The asp:menu control generates Table in asp.net 3.5. But I have CssAdapter that generate unordered-list instead. But on FF v17 its not working anymore. IE & Chrome are good. I suspect the refID property for Firefox has something to do!  

I am running on Asp.Net 3.5, so there is no RenderMode property available.
