I'm looking for the option to turn off a multi-touch feature that appears to only be available in firefox.

While pressing the alt button, if I swipe to the left, firefox will go back multiple pages. I can verify this doesn't happen in other browsers (tested on Vivaldi and Chrome), only Firefox. After searching through the options for anything involving the key "alt" "touchpad" or "gesture", I couldn't find a quick way to disable it.
