That is, unless you’re using Firefox. Firefox creators decided, in their infinite wisdom, to make left and right scrolling jump you ahead and back in your browser history. This was a dumb decision, made even more dumb when the Mighty Mouse from Apple came out. You see, using any trackball, you end up probably doing a little bit of left and right scrolling when you’re trying to scroll up and down. Trackball and Mighty Mouse users therefore go whizzing around cyberspace everytime they try to scroll a Web page.
