Son's cyber school said we should use older version

When we go to log in to my son's school, this message comes up, "This website currently only supports Microsoft Internet Explorer 7.0 or 8.0 (IE 9.0 is not supported) and Firefox 3.x. Your browser is currently not supported." How do I uninstall the current version and install the version that is compatible with his school?

Install Firefox Portable 3.6.23 to your hard drive for use at that website. It won't affect your current version of Firefox.
