 ## Compatibility
 
-### Via MSE
+The [Media Source Extensions](http://caniuse.com/#feat=mediasource) API is required for http-streaming to play HLS or MPEG-DASH.
+
+### Browsers which support MSE
+
 - Chrome
 - Firefox
 - Internet Explorer 11 Windows 10 or 8.1
 
-Using the [overrideNative](#overridenative) option
+These browsers have some level of native HLS support, which will be used unless the [overrideNative](#overridenative) option is used:
+
 - Chrome Android
+- Firefox Android
 - Edge
 
 ### Native only
+
 - Mac Safari
 - iOS Safari
 
+Mac Safari does have MSE support, but native HLS is recommended 
+
 ### Flash Support
 This plugin does not support Flash playback. Instead, it is recommended that users use the [videojs-flashls-source-handler](https://github.com/brightcove/videojs-flashls-source-handler) plugin as a fallback option for browsers that don't have a native
 [HLS](https://caniuse.com/#feat=http-live-streaming)/[DASH](https://caniuse.com/#feat=mpeg-dash) player or support for [Media Source Extensions](http://caniuse.com/#feat=mediasource).

+Since MSE playback may be desirable on all browsers with some native support other than Safari, `overrideNative: !videojs.browser.IS_SAFARI` could be used.
