hello, you can try increasing the general.smoothScroll.mouseWheel.durationMaxMS & general.smoothScroll.mouseWheel.durationMinMS preference - maybe try increasing the values by 100, 200 & 300 and see if that fits you better. you can always press the alt key while scrolling to do a super-slow scroll too...

Firefox 10 has changed the scroll amount for the keyboard navigation UP and DOWN keys to 3 lines.
You can set the scroll amount for the mouse wheel via mousewheel prefs on the about:config page, but you can't do that for the keyboard navigation keys.

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.

Thank you.

I really appreciate it.
