One option that works for me is imwheel. It is in the standard repositories.

In $HOME/.imwheelrc one can put something like:

"^.*Chrome.*$"
    None, Up, Button4, 6
    None, Down, Button5, 6

"^.*Firefox.*$"
    None, Up, Button4, 7
    None, Down, Button5, 7


".*"
Control_L, Up,   Control_L|Button4
Control_L, Down, Control_L|Button5
Control_R, Up,   Control_R|Button4
Control_R, Down, Control_R|Button5

The values 6 and 7 refer to increased scroll speed.
