Source code from Firefox below... [http://aretecapitalpartners.com/3_image002.jpg] Source code from Chrome below... [http://aretecapitalpartners.com/2_image002.jpg] Pay particular attention to where that classes are defined in Firefox (notice how there is a <font> tag around the two panels where the “TabbedPanelsTabSelected” class is assigned, whereas in Chrome, those are assigned to the <LI> tags like they should be). This means it technically is working in Firefox, but it thinks both tabs are “one” because the class is assigned in the wrong place. I don’t really know why Firefox is putting that font tag in there…. please help!
