Ask HN: Why does your web development team not support Firefox?

In the recent past, I've come across teams that consciously don't support Firefox and some of them don't even try - they will also redirect you to a page to download Chrome in some situations. This is terrible for a free and open web. Every time a team consciously decides not to support Firefox, I lose a little respect for their technology choices. How can we as a community have better support for supporting Firefox for web developers?
