Oh on the portfolio in question: http://frontsidestudio.co.uk/wp/?portfolio=caffi-cynefin
This has parallax at the top of the portfolio. Loads and looks great in Chrome and Safari but when I load it in firefox it turns out like this – see attached.
As it loads, everything is fine and lookas as it should. The page is even loading at the right length but at the last moment of loading it collapses on itself. This seems to only happen on this page and it is the only one I have used parallax on.
I look forward to your feedback. Oh I am on an imac 10.8.4 with Firefox 24.
Thanks
Wes
