Firefox Reverse/"Natural" scroll wheel direction
Raw
firefox-reverse-wheel.md

Open about:config and set mousewheel.default.delta_multiplier_y to negative, e.g. -100 if the current value is (the default) 100

This should only be necessary on platforms where Firefox isn't honouring the global setting. For instance on a Mac or Windows it's not necessary if you've set the scrolling direction to reverse globally, but on Linux, Firefox doesn't honour KDE's setting. I haven't tested GNOME ….

The default setting is fine for an actual mouse-wheel, but when using a touchpad to two-finger-scroll (or a trackball), it's more Natural for the page to scroll down when you swipe your fingers up: it seems more like how a paper page will shift.

on ubuntu 18.04 mate-desktop with natural scrolling options set for mouse and touchpad in /usr/share/X11/xorg.conf.d/40-libinput.conf

This is not necessary.

Huzzah! You made my day!

On Ubuntu 20.04 GNOME desktop, it seems to follow the global settings.

on Ubuntu 20.4 LTS installed on an old mid-2010 MacBook Pro, it was driving me nuts that I had Natural Scrolling enabled in Mouse and Touchpad settings and scrolling worked exactly like I wanted everywhere except for Firefox. Changing the mousewheel.default.delta_multiplier_y to negative, e.g. -100, worked like a charm for me. Thank you!
