yup me too, where did it go and how do i get it back, i have been very unimpressed with the recent update to make things 'better' or to see how many people actually use the tool's where you put them. your latest update seems more like a survey to see how many people venture beyond the mouse and see the qwerty thing. c'mon firefox be all that you can be!! its not hard to be better than microsoft just look and apple.

You should be able to access this recent history by holding down, for a couple of seconds, a left click on the arrows or, easier I think, right clicking on the arrow(s).

There is a new extension to restore the drop marker for those who miss it -
