How to Stop Auto Scrolling on Facebook
Some Web pages, like Facebook, will auto scroll when you place your cursor over the page. This can become annoying for pages containing lots of text or images because the page scrolls without you even wanting it to. The vertical scrolling of Web browsers and applications on your computer is controlled by the mouse settings. Disable auto scroll in Windows to allow you to scroll and navigate through pages at your own pace.
Click the Windows orb and then click "Control Panel."
Double-click the "Mouse" icon.
Click the "Wheel" tab.
Click "One screen at a time" under "Vertical Scrolling."
Click "Apply" and then click "OK."
