I just got a new laptop, and it's great. However, in Google Chrome, middle-clicking on a tab closes it, and my middle-click is activated by tapping with two fingers. Unfortunately, recognition of this gesture isn't that great and I end up accidentally closing tabs a lot - and, as my luck would have it, they're usually important.
I absolutely need the scroll wheel though. How can I disable a middle-click, which I never use in the first place, but keep the scrolling functionality?
