This is an error with the html on your webpage, not with firefox. Among other problems, your comment on the first line needs to be closed with "-->", otherwise firefox will parse the entire page as a comment.
To prevent (or diagnose) problems like this in the future, you can check that your html is valid at http://validator.w3.org/ ** Changed in: firefox (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/837646 Title: simple web page does not render in firefox (does in IE).
