I have a good idea for better firefox UI it's to make middle click assigned to autoscrolling only in the scrollbar region so that it won't interferes with what ever Linux users do with there middle mouse button most people are not aware that firefox do have autoscrolling and even when they know about it, they will disable it back because we need to copy and paste with middle mouse button and we do other things with it http://fedoraproject.org/wiki/FWN/Issue138#Firefox_Mouse_Woes middle clicking the scrollbar is not strange it's there in other web browsers like IE and opera and to make Windows users happy this limiting the autoscrolling region should be only defaults in linux ie. instead of having autoscrolling on and off we should have autoscrolling full or smart (or limited)
