Content box alignment issue with firefox

[Dan_parker]

Hey im after a little help. Im working on a vb forum and we recently installed a new skin. For some reason some of the content boxes move to the right of the screen. Im not sure who coded the skin but the person isnt around anymore. The problem is only with firefox. It works fine in other browsers. I have posted a screenshot of the problem below. Thanks for the help in advance.
