The other browsers have such low market share that it just doesn't make economic sense to bother with that. I don't like this state of affairs, but that's currently the way it is!
Also, one (small? large?) reason Firefox has lost so much market share is that Mozilla just isn't being practical. For example, here's an obvious feature they should be implementing, but refuse to do because of their whole stance on hiding behind web standards:
This works just fine in Chrome, Safari and Edge. The bottom line? No way to justify spending even more time trying to support a browser that almost none of my users actually use...
Again, I'm not trying to be a stick in the mud against a multi-browser world here. But we don't live in a world of infinite resources, and some things just don't make the cut sometimes.
