Razer Viper Mercury: Middle Wheel Click Scroll Mode Setting?

Hi there,

I purchased a razer viper mercury (the version with the cord) and there is one setting I can't seem to find:

How do I set the middle mouse wheel click to start the scroll mode?

On my former mouse it used to be that I could click and hold the mouse wheel and then move the mouse up (for scrolling up) or down for scrolling down.

I am aware I can turn the wheel to scroll, but its just not as comfortable I think I am missing a setting, hence the question.

Thanks

 

This was resolved - apparently you can turn it off in Firefox. You have to enable "Use autoscrolling" for it to be available in Forefox.
