I downloaded & installed the latest version of Firefox about a few days ago. After that, every time I open Firefox at the home page, I get this message: URGENT! Your version of Firefox is no longer protected against online attacks. Get the upgrade - it’s fast and free! Downloading and installing again doesn't help, since it's the same version every time. I've been Firefox for years and never had any problems with it before. What can be the cause of this? And is it true that I'm no longer protected?

This can happen if you have an incorrect user agent string (identifies the version of Firefox). Some add-ons can lock 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 giving conflicting information, it is "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.11) Gecko/2009060215 Firefox/3.0.3, Ant .com Toolbar 1.3 (.NET CLR 3.5.30729) "

The user agent string indicates that you have got Firefox 3.0.3, but the "rv:1.9.0.11" part of the user agent string is for Firefox 3.0.11

You need to reset the user agent string and it will then correctly identify what version of Firefox that you have installed, for the latest version it should show Firefox 3.6.13.
