Here is my first pass. I'm sure it is incomplete.

Feature Firefox Chrome IE Safari
HTML5 canvas basic 3.6 4 9 4
HTML5 canvas text API 3.5 4 9 4
HTML5 audio element 3.5 6 9 4.0-4.1
@font-face 3.5 4 9 3.2

Window.devicePixelRatio 18 4 11 3.1

"use strict" 4 13 10 5.1
DOM element addEventListener() 1 1 9 7
event.preventDefault() 1 1 9 1
event.stopImmediatePropagation() 1 1 9 1

These 4 browsers are the only ones we need to support at this time.

Please add to this list whenever you add something new that is not a universal feature in all browsers. Or add anything that you run across in our code that is not universal and which is not already in this list.

Only on the desktop platform is IE even appearing, but it is a distant 5th. Even the Windows-heavy NetMarketShare shows IE as in 3rd place on Desktop with 7.50% share (and declining).

IE is not growing and no longer represents a strategic direction from Microsoft, so we will probably be seeing many potential HTML/CSS/Javascript standards that are not supported there. We will report such limitations here. IE will be considered a "restricted support" browser from now on.

We will also keep an eye on Edge. It probably should be supported soon, especially when the Chromium version is released (shortly).

Future mobile enablement will need to consider new browsers as well.

It needs to check new versions of IE - Edge browser if it supports ORTC, navigator.MediaDevices.getUserMedia and Promise according to these articles https://blogs.windows.com/msedgedev/2015/05/13/announcing-media-capture-functionality-in-microsoft-edge/ and https://blogs.windows.com/msedgedev/2015/09/18/ortc-api-is-now-available-in-microsoft-edge/ . The older versions of IE11 - Edge don't support these features (API).
