Window title bar does not update properly

[Barry Heath]

Binary package hint: firefox

I noticed this afternoon that the Window title bar (that's the one with the Close/Minimise/Maximise buttons on) was showing the title of the first tab I opened, even after changing pages, and after closing the tab. Later the title bar changed to that of another page I had visited, but still does not update. In fact it is still showing "General Help - Ubuntu Forums - Mozilla Firefox" even though I am typing this, (fairly obviously) on the bugs.launchpad.net site. I know it's not a critical bug but it's starkly obvious and detracts from an otherwise clean interface.
System is hp G62 a29SA laptop (amd64x2, 3GB, Linux 11.04/Unity 32-bit; Firefox 4.01) Installed yesterday so your fault report is accurate.
