Logitech Set Point Problems

[Method]

Just downloaded the new updated Set Point for me Logitech G5 Mouse. Seems to have mucked up my side button.

Does anyone know what you need to do to get a click of the side button to open a new tab in Firefox with what you've clicked on?

Hope I've described that right lol.

apparently uberOptions only runs with set point up to version 4.80 and this new one is 6.00, tried it and assigned the Ctrl + Alt + T , which is the Firefox shortcut for opening a new link in a new tab and try to assign it to the middle button of the G5. Doing me head in
