Fixing the middle button for Logitech mx510 in Firefox

Logitech mx510 is an awesome mouse and it works out of the box in both Windows and Linux. However, to unleash it's full potential in Windows, one has to install the bundled SetPoint software.

Once SetPoint is installed, the mouse starts showing a really nasty habit - the middle button, when used in Mozilla Firefox, no longer opens a link in a new tab.

The fix is not overly obvious: in SetPoint application, one has to change the function of the middle button (Autoscroll) to "Other" and choose the "Generic Button" function. This fixes the problem.
