Bug 1363508 - Part 1: Spoofing pen/touch pointer events into mouse pointer events when fingerprinting resistance is on r=arthuredelstein,masayuki,smaug The pointerType field in the pointer event will reveal the details of users' hardware; this is a fingerprinting vector. So, we would spoof all types of pointer events into mouse type pointer events for protecting users from browser fingerprinting when fingerprinting resistance is on. In this patch, we would spoof the pointerType as well as other fields that mouse pointer events don't support, like pressure, tiltX/Y and so on when fingerprinting resistance is on.
