Mousewheel not scrolling and config settings appear to be OK, is this a FF17 thing or what?
Of the few solutions I have read, all talk about slowness or some other performance issue - my mouse wheel scrolling has stopped altogether and nothing I have tried works, including restarting with add-ons disabled and checking the config.

You can set the scroll amount for the mouse wheel via mousewheel prefs on the about:config page
mousewheel.withnokey.numlines = 2 mousewheel.withnokey.sysnumlines = false
Look at this pref to set the scrolling behavior with the keyboard.
toolkit.scrollbox.verticalScrollDistance (3)

There are extensions that work both for the mouse and the keyboard to set the scroll amount, but they can only be set to scroll an amount of pixels and not to scroll one line regardless of font-size (height) of the text.
