Vertical Scrollbar missing in Firefox for Flash 8 website

Hi,
I have a website that I designed in Flash 8 (AS2) but when I upload the files onto the web the vertical scrollbar is missing in Firefox. I had fixed this problem before by linking the HTML file created by Flash to a CSS file and changing a couple of things in the HTML file to reflect to link to the CSS. See below. The text in pink is just changing the html to css and the text in blue is to centre the website vertically. It worked before but now it wont work I don’t know what’s wrong. Am I missing something? The swf,css and html files are all uploaded to server so I don’t know what is wrong. I can PM the website name to any replies. Thanks
