For chrome and firefox there is an extension I use that helps dramatically. "Scrollbar Anywhere".
The way I have it set up, I can right click and drag anywhere on "whitespace" on the page and scroll in any direction I drag the mouse. You can set it up to go as fast or slow as you like relative to the amount you move your mouse, and you can even have it "glide" when you let up on the mouse if you like.
