If you have upgraded to Mozilla Firefox 0.9.1 you might have noticed a little icon in the status bar alarming you about some critical updates that are available. The only problem is that it is reporting that there is a upgrade called Mozilla Firefox 0.9.1 which you already have installed...

1. Type about:config in the address bar [enter].
2. Make a filter for update.app

4. Restart Mozilla Firefox
