Current Firefox versions no longer use that Google site as the home page, but use the build-in about:home page as the home page. So Google assumes that you use an older Firefox version if you still visit that site and warns you about that and suggests to update. You can use another page as the home page like about:home or www.google.com or www.google.com/ig (iGoogle)."
