Mouse wheel scrolling has been implemented on several computer mouses to make the navigation faster and easier. It saves your time by moving the page either upward or downward. By default, the mouse wheel has been designed to scroll three to four lines each time you roll it through a web page. However, not everyone like to scroll the mouse with certain number of lines, you might want to make the scrolling speed faster or slower. If you are a Firefox user and want to adjust the speed of your mouse scrolling, here is the tutorial for you.
In order to make a slow mouse scroll or fast mouse scroll, you have to manually change the scrolling settings and adjust the speed from configuration settings menu. Simply launch your Firefox browser, type about:config in the address bar and press Enter to continue.
It will pop up a warning window with a message like “changing these advance settings can be harmful to the stability…”. Click I’ll be careful, I promise! button to continue.
