Drag to scroll does not work in Firefox
Using the web browsers Internet Explorer and Edge and/or Chrome, you can drag an item to the bottom of the window and the content scrolls up which allows you to drag the item below the visible area. Firefox does not natively support this browser feature, however, an add-on is available from Mozilla that adds this functionality. You can download the add-on from the following URL: https://addons.mozilla.org/en-US/firefox/addon/drag-to-scroll-reloaded/.
