1108440 - Firefox doesn't honor FlipFlopWheel registry setting on Windows for non-privileged pages

Status: UNCONFIRMED

(Core :: Widget: Win32, defect)

Description

[ruurdross]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141113143407

Steps to reproduce:

In Windows 7, I have reversed the direction of vertical scrolling using this registry change: http://superuser.com/questions/310681/inverting-direction-of-mouse-scroll-wheel
This change ensures that scrolling 'up' with the mouse wheel makes something really scroll up - like the default for Mac OS X.




Actual results:

This works fine now in most Windows programs. In Firefox however, the scroll direction on web pages is still reversed. Firefox' about:config page however scrolls in the correct direction.
I have now changed mousewheel.default.delta_multiplier_y to -1 so web pages scroll correctly. Now however, the about: pages scoll in the wrong direction.


Expected results:

Without having to change anything in about:config, all Firefox pages should scroll in the direction set in the Windows registry.
