Johnny Matthews | Disable touchpad scroll-zoom in Firefox

It’s super annoying when you’re scrolling down a window and press CTRL for whatever reason. The whole window freaks out and starts zooming in. I don’t really want this to happen, so here’s how to disable the scroll-zoom in Firefox. This was written on 9th of June 2020.

It’s silly and I don’t like it.

  1. Go to about:config in Firefox.
  2. Search for mousewheel.with_control.action and change it to 0.
  3. Search for mousewheel.with_meta.action and change it to 0.

If you use Firefox Sync and want it to stick, add the following variables as boolean and set them to true:

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

That’s about it! You should now have successfully disabled the touchpad scrolly thing.
