Changes

GeckoView is a library, not a standalone app, but you can test GeckoView by installing Focus Nightly "track" (channel). Focus 6.0 and earlier use Android's WebView, but Focus 7.0 is switching to Mozilla's homegrown Gecko. Unfortunately, Google Play only allows you to install one track (per Google Play account) at a time. Installing Focus Nightly will uninstall the regular Focus and replace it (and your settings) with Focus Nightly. If you have multiple Google Play accounts, then you can install a different Focus track in each account.

* If you've found a bug in Focus Nightly compared to Focus using WebView, then check the [https://github.com/mozilla-mobile/focus-android/issues Focus bug tracker] to see if there is a bug filed. If not, please file one! :)
