问题
I have a page that when it loads in firefox 8.0 some users report the layout is all distorted. Clicking refresh fixes the issue. I can't figure out how to test this since it displays just fine on my machine. No reported Javascript errors, and again, it works fine after pressing F5

As others have said in the comments, it is a caching issue, some users are using your site with an old version of your css.
Always use the version number of the website to avoid the issue in the future
<link rel="stylesheet" href="/include/css/site.css?v1.01" type="text/css" />
