Allow customization icon for Android

With Firefox having a dark background for the icon on Android, it makes the icon look tiny on a lot of wallpapers.

It would be great if there was an option to simply change the icon to have a white background instead for those of us who like to use darker wallpapers.

If you were to add extra icons option, I'd love Preview icon to be added as well, I really enjoyed it!

I think the Background should be changeable (light/dark/transparent).
