Does what it advertises, which is good.
However: Firefox 8 pulldown menus (e.g. the Bookmark list) are no longer useable, as the pulled-down menu disappears when the mouse is moved.
AlertBox is not messing with any of your pull down menus. Check other addons that you have installed or restart Firefox with all addons disabled to find the offending one.
