Firefox doesn't fucking work with my daughter's online school. This is a national school that multiple states are adopting as a state online school (meaning it is a public school and we don't have to pay tuition) and we have to use Chrome because I can't get it to work in Firefox and I hate Edge. Even worse, a bunch of materials from the school either don't mention which browser to use or specifically say you can use either Firefox or Chrome. I spent like half an hour trying to figure out why it wasn't working. I did updates, resets, anything I could think of, until my wife texted me and said maybe it has to be in Chrome. And yep, that worked.

Of course, the school is run by Pearson, and they're evil, so they probably have a deal with Google anyway.
