Cannot login to Firefox on desktop PC

I have installed FF on my new laptop and successfully signed in with my email and password. Based on this success, I have reinstalled FF on my desktop where sign in stopped working a year ago. And it still does not work, it keeps asking for master password. I cannot remove the account. The correct password, that works on the laptop fails to work on the desktop. Refreshing FF keeps one thing: the account. FF keeps bugging me about the master password on the desktop. And it does not accept the correct password.

This entire password handling is a great mess on FF.

What to do?

Each device can have its own Primary Password. Firefox stores the credentials to login automatically to the Mozilla Account in the Password Manager, that is why Firefox would ask for the PP. You will have to reset the PP if you do not remember it.

That is very strange, because I could log in to FF from my new laptop. Still cannot login from my Desktop that has had the same Windows for years. Even after reinstall, the account is there and cannot even be removed. This design is not just strange, but it basically locks me out from FF on this PC. I will use another product, because this is just terrible design.
