<p>[1] Touch events were implemented in Gecko 18.0, but removed again in 24.0 {{geckoRelease("24.0")}} on the desktop version of Firefox due to web compatibility issues ({{bug(888304)}}).</p>
<p>[2] As of Gecko 52.0, touch events support has been fixed and reenabled in Windows desktop platforms.</p>
