Visit Firefox Marketplace through Android
The current Aurora version of Firefox for Android has bleeding-edge features that may not be stable. It isn’t available from the Google Play store -- only through Mozilla’s site. And you can only install it on Android devices that permit you to “sideload” apps that are not authorized by Google. Once you have it installed on your Android device, and you launch it, open the browser’s settings menu, and tap Apps to launch Firefox Marketplace.
