@asvwebdesign You’re right. The Tabs on your site don’t react. And they are listed instead of hidden in tabs. This looks very much like a non closed tag somewhere in your code from my point of view.
I’m currently working on a new page and there is no trouble with tabs whatsoever.
@ferewulf On the two links I get your pages (massive load of data) with no problem. Tabs are working fine here (Firefox 41.0).
