The fafsa.gov site does not currently support Firefox newer than version 3.6.x. That is their choice.

You can install Firefox Portable version to use only on that site and use your installed current Firefox version for everything else. Firefox Portable is not produced by Mozilla (but is based on Firefox released versions) and is not supported on this site -- has its own support forum (see below). Firefox Portable installs in a separate folder on your hard drive so that it does not interfere with your currently installed Firefox version settings or personal information (bookmarks, passwords, etc.). You can also install Firefox Portable on a USB/thumb/pin/jump drive.
