Provide preference to set delta
Mode value of DOM Wheel Event
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:17.0) Gecko/20100101 Firefox/17.0 Build ID: 20121128204232 Steps to reproduce: As documented in https://wiki.mozilla.org/Gecko:Mouse_Wheel_Scrolling#Mozilla_17_.28Firefox_17.29_or_later Firefox 17 no longer provide a way to scroll by pixel in response to a mouse wheel event Actual results: In Firefox 16 and below, setting mousewheel.withnokey.action to 4 allows per pixel scrolling in response to a mouse wheel event. I use this under Linux to have Firefox respond to trackpad scrolling events by translating them into mouse wheel events. Expected results: Please provide a preference like mousewheel.default.deltaMode which can be set to pixel, line or page to override the OS specific behavior that is currently specified.
