I thought it might be a Firefox rendering issue – and it partially is. Firefox compresses the post titles down to a vertical column that is hard to read. And right now I’m posting this via Google Chrome 27.0.1453.116.
But it looks as though WordPress has made some changes. I hate the new layout for blog admin btw. But better – a feature that replicates across Firefox 22 and Chrome 27.0.1453.116 – when you go to EDIT a post it loses the text of the post in the editor.
So to the folks at wordpress – fix it please.
