Firefox says I'm running the latest browser version, yet when I try to fill out a FAFSA application (at fafsa.ed.gov), I am directed to a page with the following message: "An Incompatible Browser Has Been Detected: Your Web browser is not supported by our Web site. You must use a Compliant Web Browser - Standard* to view our site properly. We recommend you upgrade to the latest version of your browser according to your Operating System." I can't find an older version to download. Please link to a page with the proper version. The page recommends Firefox 3.5x or 3.6x for Windows 7.
