I can no longer access my NatWest website
For years I have used Firefox and been able to login to my NatWest Account - suddenly I am no longer able to have this facility. SECURE CONNECTION FAILED - The connection to the server was reset while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data couldn't be verified. Please contact the owners of the website to inform them of this problem.
I looked on your help site to see if there were others with this challenge and found some comments from some sanctimonious prat to the effect that this should be remedied by the website owner and that eventually the website would no longer be able to be accessed by any other browser such as Chrome, Edge etc. Great, but I need to see my bank accounts online and rather than change banks, I am changing to Edge so that I can. Eventually NatWest may have to change their security but until then I am going to move away from Firefox, and, I know I only contribute a small amount to your "cause" every year but I shall take that away as well - you are too "holier than thou" in your approach to security and take no thought of how its implications affect the user.
The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.
If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.
And no one takes well to intimidation, so please stop it.
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
