You have a user agent that identifies you as Firefox/3.6.21

  • Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2.21) Gecko/20110830 Firefox/3.6.21 GTB7.1

You can check the general.useragent.override pref on the about:config page and reset the value to the default via the right-click context menu.
