For Verizon, it's one of their log in forms that doesn't work on Firefox, even with ublock disabled. Works just fine with Chrome. I was able to reproduce the behaviour on both my and my wife's laptop. (I haven't tried disabling the FF privacy features)

Rereading what I wrote, I see the unintended humour in my association.

That being said:

1. These are both websites where I don't have much of a choice whether I use them or not

2. I actually expected Verizon to have a terrible website based on the sum of my interactions with them (both online and over the phone) and how uncompetitive the market is. But I was surprised the kindergarden had a needlessly restrictive website because I thought they'd care more about their online presence. And, to be clear, the kindergarden's website is fancy and expensively designed, so their lack of Firefox support can't easily explained by laziness.
