Disable Firefox’s zoom on mouse scroll

less than 1 minute read

This annoys me endlessly as I seem to often have my hand on control / cmd from working in the terminal.

Turns out it’s an easy fix in Firefox’s about:config:

mousewheel.with_control.action 0
mousewheel.with_meta.action 0

And if you use Firefox Sync and want those settings to sync between your devices also add:

services.sync.prefs.mousewheel.with_meta.action true
services.sync.prefs.sync.mousewheel.with_control.action true
