I am homeschooling my child with the K12 Texas Virtual Academy. They require that my computer have Firefox Version 3x. Do I downgrade to V.3x?

If it is just one thing then you may be better off using the Portable Firefox version of Firefox 3.6.* as it will not impact your Firefox 6.0.2 install and settings. It is self-contained as you can you can install it on hard disk or on a usb flash drive.
