A mouse wheel or a scroll wheel is created for easy scrolling and better navigation. It is very handy and helpful especially when you scroll up and down long pages. By default, the mouse wheel move up and down three to four lines each time you roll it through a webpage. You might get frustrated due to the slow scrolling speed and perhaps a faster pace will be ideal. If you are using the Firefox browser, Mozilla offers users a simpler way to adjust and modify the browser’s default scrolling speed.

To change the default mouse wheel’s scrolling speed, users need to edit the browser’s configuration setting in the about:config entries. To edit it, users just need to access the Firefox browser, then type about:config in the address bar and press enter to continue.
