HAving successfully upgraded to v4 on my vista based laptop when I tried to upgrade to v4 on my XP based desktop, although the wizard appeared to work correctly it has left me on v3.6 - why?

On my XPbased desktop I downloaded the Firefox set-up 4.0, ran it and the wizard launced and appeared to work, and when I clicked "Finish" with the "Launch Firefox" button clicked, I was left on the old version , 3.6. The upgrade worked perfectly on my Visa based laptop.

You probably have Firefox 4 on Windows XP, but Firefox 4 on Windows XP will be displaying the old style UI. The new interface is only default on Windows Vista and Windows 7. To get it on Windows XP you need to hide the menu bar. To do that in the View menu select Toolbars, then click on the "Menu Bar" entry.

If you need access to the menus you can press either Alt or F10 to temporarily display them.

Thanks very much - that appears to have resolved the problem. What was confusing me that the old v3.6 Firefox home page was still warning me that I was on an old version and needed to update!
