[1] Touch events were implemented in Gecko 18.0, but removed again in 24.0 (Firefox 24.0 / Thunderbird 24.0 / SeaMonkey 2.21) on the desktop version of Firefox due to web compatibility issues (bug 888304).
[2] As of Gecko 52.0, touch events support has been fixed and reenabled in Windows desktop platforms.
