Why do I have Firefox- problems with NordVPN, Consumentenbond and several Bankaccounts????? Some apps advice me to login via Chrome or Edge!!!!!

- Why do I have these problems?

- Am I the only one? (then it probably is my machine and / or I the cause)

- What can I or FireFox do about it??

I have a issue with banking and some medical sites. I find only FF Private browsing works. I talked to my bank's support and they told me change over to Chrome and I don't like being forced to change Browser's!
