How do I enable middle-click scrolling in firefox?

[449]

Before I could find it at about:config ,but now I cannot locate it. How do I do I enable scrolling for the middle mouse button in Firefox 3?

Go to Edit->Preferences->Advanced->General. Now, under the "Browsing" section, check the "Use autoscrolling" box. This will enable the middle-click scrolling that you want.

Sweet. I was missing that too.

Does anyone know how to make the side buttons on my 5 button mouse to be "Forward" and "Back" buttons in FF3? This works in Firefox2 still if I choose to run that.
