Woot, scrolling in Firefox on Ubuntu using middle mouse button

Thanks to Pete for this tip - with his help ( and some Googling ), I was able to configure the middle mouse button ( on a Thinkpad T60p ) to allow me to scroll through a web page in Firefox.

Simply put, open Firefox, navigate to the address bar and enter the URL about:config. Assuming you're happy to proceed past those dragons, change the setting general.autoScroll to true. Once you restart Firefox, you're good to go.
