Increasing scroll speed

I have a wireless mouse, and the scroll sensitivity - especially in firefox - is set way too high.

Is there a simple way to decrease it? Right now, the slightest touch on the wheel jumps to the bottom of the page. It's a Microsoft Wireless Laser Mouse 5000 if that makes a difference. (I also have a wireless logitech mouse attached to the same system, and the scroll speed is fine - if it wasn't for a bad button, I'd be happy to keep it.)

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I'm only aware of a way to fix this within Firefox itself, not Ubuntu-wide.

In your address bar, type about:config and then change mousewheel.withnokey.sysnumlines to false and mousewheel.withnokey.numlines to a number smaller than the default of 6.

Unfortunately, it doesn't seem that Ubuntu's Mouse Preferences has a way to change the scroll wheel's behavior. You can find Mouse Preferences by hitting the Super key (or Windows key) and typing Mouse.

not sure how to get there in Unity. But If you log in With Ubuntu classic from the log in screen. Then go to System > Prefences > Mouse Settings there you can slow it down or speed it up

This did not work for me, I was still not able to access the scroll-wheel properties in classic, just the mouse movement speed which is different. – Michael Durrant Feb 6 '12 at 16:11
