First, It should had a option button in extension manage page that users can enter the option page and change the setting. It difficult to be noticed that users can discover the "drag-to-open-setting-page" area when they are dragging anything and can open setting page after they move to the area and release.
Second, it will do nothing in firefox 4.0 after I drag something, move to the "dgag-to-update" area in textbox and release...
