Chrome has this option of scrolling just a little when you press alt+up/down arrow, on Firefox at least on MacBook I have to press fn key, very inconvenient, how to change it to alt?

There are prefs that set the mousewheel action for various modifiers. You can modify the delta_multiplier_y pref for a specific modifier to a lower value to scroll less and set its action to '1' to scroll.

Mousewheel prefs:

  • mousewheel.default.action
  • mousewheel.with_*.action
  • mousewheel.with_alt.action = 2
  • mousewheel.with_control.action = 3
  • mousewheel.with_meta.action = 1
  • mousewheel.with_shift.action = 4
  • mousewheel.with_win.action= 1

Action:

0: Nothing happens
1: Scrolling contents
2: Go back or go forward, in your history
3: Zoom in or out (reflowing zoom)
4: Treat vertical wheel as horizontal scroll
5: Zoom in or out (pinch zoom)

I don't want mousewheel I want arrow up/down +alt to scroll like it's in chrome.

Ok I adjusted this toolkit.scrollbox.verticalScrollDistance from 3 to 40 so I just press arrow up/down it scrolls more.
