The Google Toolbar no longer works as expected after upgrading to Firefox 4. If I begin to type in the search box, suggestions start to appear (as they should), but if I try to select one with the mouse, nothing happens. I either need to use the keyboard cursor key to move down the list, or type the entire term in the box and then begin the search. But I cannot select anything with the mouse. This occurs in all versions of Windows (XP, Vista, W7).
