Scroll Menus On Drag is a Firefox extension which scrolls menus when dragging, fixing bugs 194319, 240709, and 349932.
Scrolls all autorepeatbuttons and prevents bookmarks menu hiding on all menuseparators.
When menus are too big to display, autorepeatbuttons (arrows) are added to the top and bottom of the menu.
They scroll the menu when when hovered over, but not when something is dragged over them (https://bugzilla.mozilla.org/show_bug.cgi?id=194319).
This extension works around that, until bug 194319 is fixed. It also prevents premature bookmarks menu hiding (bug 349932).
