Firefox on Mac tip for trackpad users

In Firefox on Mac, if you double tap to zoom (smart zoom) on something (for example, a column of text), by default, and unlike Safari, the scrolling is very “loose,” making it very difficult to scroll in a straight line. But if you change `apz.axis_lock.mode` to `1` in the advanced settings (`about:config`), it makes the scrolling very stable, linear, at least as much as Safari, maybe more.
