Hi wingfoote, As of writing this reply, Firefox 11.0 is the latest official release. You can find it here: http://www.mozilla.org/products/download.html They also offer Beta, Aurora, and Nightly builds. If your school does not support the newer versions of Firefox, you can take a look here: http://www.mozilla.org/firefox/all-older.html It looks you are already running this version though. Hopefully this helps!
