Some websites, including Firefox Help, tell me that I still have Firefox 3.6 when I have updated to 9.0.1 and that is confirmed in "About Firefox". What's going on?

Many websites that I go to have pop ups that tell me I need to up date to a newer version of Firefox because 3.6 is no longer supported and has security problem. I have updated multiple times over the last 3-4 months or more, and I still get this message. In the "about firefox" area it confirms that I have 9.0.1

Your User Agent shows that your are using Firefox 3.5.3; click "More system details" to the right of your original question and scroll down to see:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 FBSMTWB

See --> https://support.mozilla.org/en-US/kb/Finding%20your%20Firefox%20version

The problem with your User Agent being changed could be caused by Fast Browser Search (FBSMTWB) being installed on your system:
Remove Fast Browser Search

THEN, reset your User Agent:
