Hi! I'm also a Firefox loyalist and have been searching desperately for this functionality. I've seen all sorts of options that *sort of* indicate that it *might* be available but nothing works.
Some webpages I've viewed: - https://wiki.mozilla.org/Gecko:Mouse_Wheel_Scrolling#Preferences_for_customizing_delta_values_and_default_action - http://forums.mozillazine.org/viewtopic.php?f=23&t=2072387 - https://wiki.mozilla.org/Gecko:Mouse_Wheel_Scrolling - http://forums.mozillazine.org/viewtopic.php?f=38&p=12546047 These pages are related to this feature request but none of them provide an actual solution. User @Skewer's original comment near the top of this issue says: > Note that the traditional defaults are: > Mouse wheel: Scroll vertically > Ctrl+wheel: Zoom > Shift+wheel: Pan (scroll horizontally) The shift+wheel action (Pan / scroll horizontally) is *exactly* what I'm looking for.
