This can happen if you have an incorrect user agent string (identifies the version of Firefox). Some add-ons modify the user agent string causing it to show an old version of Firefox even if you have the latest version installed.

Your user agent string is:

Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.13) Gecko/20101203 YFF35 Firefox/3.0.10 NET_mmhpset ( .NET CLR 3.5.30729; .NET4.0C)

It has been modified by an add-on and is now stuck at showing Firefox 3.0.10, but the "rv:1.9.2.13" part of the user agent string shows you are using Firefox 3.6.13

You need to reset the user agent string so that it will correctly identify the version of Firefox that you have installed, for details of how to do that see https://support.mozilla.com/kb/Websites+or+add-ons+incorrectly+report+incompatible+browser
