Pretty sure it is a problem with your PC.
I use my Win 7 PC for banking with Firefox, a couple of months ago Firefox prevented me from logging on to my bank due to a security problem with its website, spoke to the bank but they could not resolve it.
Tried Chrome and it worked.
I have a new laptop that came with Win 10 and Chrome and that worked, loaded Firefox onto it and that also worked so it is a problem with Firefox on my PC, only affects my banking website.
