Middle Mouse Button Scroll 作成者: Стоян Димитров

Scroll fast or precise through long documents with pressed middle mouse button.

Holding down Alt or Ctrl dragging with middle mouse button enables you to use the browser's implementation of middle-click scroll.

Holding down Shift dragging with middle mouse button enables you to scroll slowly and precisely.

Note: For the time being the extension scrolls only the whole page and not different parts of it. If you are unable to scroll given page that's the reason why. That feature is planned.

Also, for the time being the keyboard keys are non configurable. The current implementation of Firefox for configurable hotkeys can not use only modifier key (Ctrl, Alt, Shift, Meta etc.) for shortcuts.
