Your useragent says you are running 3.6.26 - this is the latest version of 3.6 branch, but the latest version of Firefox is 10.0.1. You should consider upgrading to the latest version. What is telling you to update? A webpage? What URL? If you have installed version 10.0.1, then your useragent is messed up and you should do the following: * Type about:config in the URL bar and hit Enter * If you see the warning, you can confirm that you want to access that page. * Filter = general.useragent. * Right-click the preferences that are bold, one line at a time, and select Reset. * Then restart Firefox
