Lots of doom and gloom comments here, but the post only refers to ending support on amazon echo and fire tv. The experience of using a(ny) browser on those devices was terrible. They probably saw usage numbers on those two devices were so low that support made no sense.
I wouldn't browse HN on my FireTV, but it's great for live streams of various events, which seem to exist on a zillion different websites (I just watched a wedding this morning on my FireTV using Firefox)
The most important and easy thing to miss is probably that this is on "DEVICES" not on "Tablets." You can still run it just fine on the color Amazon Android-based handhelds, it's the "IoT" category devices where it's going away.
Honestly I wouldn't have predicted better than a 50% chance that Firefox ran on those anyway.
