ScrollyFox is a super-simple Firefox add-on that allows you to auto-scroll through a webpage in just a mouse-click.
The app is very uncomplicated, with only a tiny selection of configuration options - you can set scrolling speed and choose whether or not you want ScrollyFox to reverse scrolling direction when it hits the end of a page.
ScrollyFox will place a small icon in the bottom right of your browser. Left-clicking will enable or disable the scrolling function, while a right-click will call up the preferences window. Unfortunately, ScrollyFox doesn’t seem to work with Google Reader, something that people tend to spend a lot of time scrolling through.
Some would argue that Firefox already has a scroll function (middle click and release), making ScrollyFox obsolete. Even so, there may be some situations in which a totally mouse-free scrolling experience is preferable. If that's the case, ScrollyFox is an effective and easy application that will do the job perfectly.
ScrollyFox makes Firefox scrolling completely automatic.
