Edit: Actually it appears your useragent is stuck at a old version. Firefox 4.0 and newer UA is not affected like this.
Acording to your System Details: User Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.17) Gecko/20110420 Firefox/3.6.17 ( .NET CLR 3.5.30729) FBSMTWB
See this on how to reset the UA: https://support.mozilla.org/en-US/kb/websites-say-firefox-outdated-or-incompatible#w_firefox-is-showing-the-wrong-user-agent
What is the website that is saying you have a older version?.
Is it say http://www.google.com/firefox ? as this used to be the old Firefox start homepage (not maintained by Google anymore) up till Firefox 3.6.28 as it has been about:home ever since Firefox 4.0

You may need to clear the preference that is misreporting your version number. See: How to reset the default user agent on Firefox.
Also, the "FBSMTWB" that appears in your current user agent string (you'll see it in about:config when you venture in there) is associated with an extension that many people find annoying -- unfortunately I can't recall which one it was.
If you haven't reviewed your extensions for a while, you might want to see whether any deserve to be disabled or removed, particularly if they are nonessential or unrecognized. To open the Add-ons page, either:
- Ctrl+Shift+a
- orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions.
Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Hope that prevents your user agent from being changed back to that old version.
