Fórum podpory Firefox

I have a constant problem with Chase.com - they are telling me it's Firefox, then it's because of the cookie blockers on FireFox. I have heard every excuse under the sun. I try to login, I get chase doesn't recognize device, then they send a one time code, which doesn't work, so I have to call them, they tell me it's Firefox causing the problem. I know that's a myth because the same thing happens on MS Edge. Is anyone else having this problem? Do you have any suggestions?
