[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.

[3] In order to prevent event handlers for touchstart from blocking rendering during the scrolling of the document or window, Chrome and Firefox have changed the default for the passive option for addEventListener() on these events to true.
