I have upgraded to to Firefox 8.0.1 but a number of sites including Googmail think I have an old version. On this site I get warnings about having 3.6 which is about to have its support discontinued but I stopped using 3.6 years ago.

Opening the "educated guesses" section below it thinks i have Firefox 3.5.7 and Windows XP when I actually have Firefox 8.0.1 and Windows 7. Hmmmm :)

Your UserAgent string in Firefox is messed up by another program that you installed.
http://en.wikipedia.org/wiki/User_Agent

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
