I hold down option and swipe up or down with two fingers on my trackpad, and Firefox is navigating forward and back in history. How do I disable this behavior? (I am using version 57.0 on Mac OX 10.13.1)

I have tried disabling the Mac system preference for "swipe between pages", and I have tried changing the value of browser.gesture.swipe.left and right to cmd_scrollLeft and Right (as described here). Neither of these solutions addressed my issue.

I found the solution:

After going into about:config, set mousewheel.with_alt.action to 0.
