I fairly regularly come across websites that are broken even in normal Firefox, like, even on Hacker News. I've had to use Chrome for some local government stuff but I reckon they broke Firefox on accident rather than on purpose and hopefully it is fixed now. Google's own Cloud Console was unusable in Firefox for a couple weeks a few years ago :) This is very different from sites not explicitly supporting Firefox, but it does happen. If I think of/find an explicit example of something broken right now I will link it here.

To be completely fair, some of it isn't really by choice. Like, the qmk configurator doesn't support Firefox, but that's because it needs APIs Firefox intentionally doesn't have. Should Firefox have these APIs? The WebUSB thing doesn't personally bug me the way Chrome implements it so I'd say sure. I'd certainly prefer having that over EME.
