Firefox just shows gray boxes. Both browsers are the latest available: 71.0.3578.98 for chrome and 63.0.2 for firefox. Automatic updates are on as is the default, I think, for everybody. There are no pending updates right now for anything. I'm using the android that came with the phone, which is stock android 7.

Anyway, the point of my post was to show that "you can use almost anywhere" should be taken with an appropriate amount of salt. I take a spoonful.
