That's strange. Your address bar has been taken over by something different? Could you check the following tab for any unknown or recent additions, and disable ALL nonessential extensions? orange Firefox button (or Tools menu) > Add-ons > Extensions category After restarting, any change? You also could try customizing the toolbar in case the standard URL bar needs to be restored (drag it from the dialog back to the bar). To get started, either: * right-click a blank area of the tab bar > Customize * tap the Alt key > View menu > Toolbars > Customize And finally, if it's a matter of the standard Navigation Toolbar being hidden and replaced by a different bar, you should be able to use these to turn bars on and off as desired: * right-click a blank area of the tab bar * tap the Alt key > View menu > Toolbars Any luck?
