I imagine the overlap of people who use Snapchat and people who use Firefox is pretty small, they probably see such a small amount of users with Firefox and they just decided not to support it.

In this day and age it’s more work to explicitly not support a browser than it is to support it…

Sort of. I imagine the idea is they only need to test on Chromium-based browsers.

So often just swapping the user agent from Firefox to Chrome makes these sites work flawlessly. So they’re putting in extra code to detect Firefox and serve a “we don’t support your browser” when they could just… not. And if a user complains about X, they could say we don’t test on Firefox, try on Chrome.

Yeah, but by putting up the “we don’t support this” banner, they won’t have to deal with the complaints in the first place.

It’s also possible they want people to use Chromium for telemetry or other data-collection reasons, not sure.

I wonder if it’s possible that they’re paid money by Google to not support Firefox?
