* '''Platform''': Implement CSS Device Adaptation to rationalize mobile viewport code ({{bug|747754}}).
 
Notes:
 
* Just implementing Touch Events and touch-action (without Pointer Events) would allow efficient Pointer Events polyfills, and other developer benefits (including ability to improve responsiveness of touch UIs).  This is what Chrome is currently doing.
* Implementing APZC on desktop would allow desktop Firefox to share much of the Touch Events / Pointer Events / touch-action code with Firefox OS.
** Similarly, porting Firefox for Android to the Gecko APZC and meta viewport code would allow increased code sharing with Firefox OS.

Android yes no no (bug 1029631) Java (bug 776030) Java (bug 799585)
Firefox OS yes no no (bug 960209) Gecko APZC Gecko
Linux no mouse only (nightly) no disabled (bug 1013364) no
Mac no mouse only (nightly) no disabled (bug 1013364) no
Windows desktop disabled (bug win-touch-issues) mouse (nightly)
touch (nightly + APZ) 		no (bug 1001440) disabled (bug 1013364) no
Windows metro yes yes (disabled) yes Gecko APZC Gecko
